Yes No. Your game will start after this message close. Current causes several observable effects, which historically were the means of recognising its presence.
That water could be decomposed by the current from a voltaic pile was discovered by Nicholson and Carlisle in , a process now known as electrolysis.
Their work was greatly expanded upon by Michael Faraday in Current through a resistance causes localised heating, an effect James Prescott Joule studied mathematically in The level of electromagnetic emissions generated by electric arcing is high enough to produce electromagnetic interference , which can be detrimental to the workings of adjacent equipment.
In engineering or household applications, current is often described as being either direct current DC or alternating current AC. These terms refer to how the current varies in time.
Direct current, as produced by example from a battery and required by most electronic devices, is a unidirectional flow from the positive part of a circuit to the negative.
Alternating current is any current that reverses direction repeatedly; almost always this takes the form of a sine wave.
The time-averaged value of an alternating current is zero, but it delivers energy in first one direction, and then the reverse.
Alternating current is affected by electrical properties that are not observed under steady state direct current, such as inductance and capacitance.
The concept of the electric field was introduced by Michael Faraday. An electric field is created by a charged body in the space that surrounds it, and results in a force exerted on any other charges placed within the field.
The electric field acts between two charges in a similar manner to the way that the gravitational field acts between two masses , and like it, extends towards infinity and shows an inverse square relationship with distance.
Gravity always acts in attraction, drawing two masses together, while the electric field can result in either attraction or repulsion.
Since large bodies such as planets generally carry no net charge, the electric field at a distance is usually zero. Thus gravity is the dominant force at distance in the universe, despite being much weaker.
An electric field generally varies in space,  and its strength at any one point is defined as the force per unit charge that would be felt by a stationary, negligible charge if placed at that point.
As the electric field is defined in terms of force , and force is a vector , having both magnitude and direction , so it follows that an electric field is a vector field.
The study of electric fields created by stationary charges is called electrostatics. The field may be visualised by a set of imaginary lines whose direction at any point is the same as that of the field.
This concept was introduced by Faraday,  whose term ' lines of force ' still sometimes sees use.
The field lines are the paths that a point positive charge would seek to make as it was forced to move within the field; they are however an imaginary concept with no physical existence, and the field permeates all the intervening space between the lines.
A hollow conducting body carries all its charge on its outer surface. The field is therefore zero at all places inside the body. The principles of electrostatics are important when designing items of high-voltage equipment.
There is a finite limit to the electric field strength that may be withstood by any medium. Beyond this point, electrical breakdown occurs and an electric arc causes flashover between the charged parts.
The field strength is greatly affected by nearby conducting objects, and it is particularly intense when it is forced to curve around sharply pointed objects.
This principle is exploited in the lightning conductor , the sharp spike of which acts to encourage the lightning stroke to develop there, rather than to the building it serves to protect  : The concept of electric potential is closely linked to that of the electric field.
A small charge placed within an electric field experiences a force, and to have brought that charge to that point against the force requires work.
The electric potential at any point is defined as the energy required to bring a unit test charge from an infinite distance slowly to that point. It is usually measured in volts , and one volt is the potential for which one joule of work must be expended to bring a charge of one coulomb from infinity.
An electric field has the special property that it is conservative , which means that the path taken by the test charge is irrelevant: all paths between two specified points expend the same energy, and thus a unique value for potential difference may be stated.
For practical purposes, it is useful to define a common reference point to which potentials may be expressed and compared.
While this could be at infinity, a much more useful reference is the Earth itself, which is assumed to be at the same potential everywhere.
This reference point naturally takes the name earth or ground. Earth is assumed to be an infinite source of equal amounts of positive and negative charge, and is therefore electrically uncharged—and unchargeable.
Electric potential is a scalar quantity , that is, it has only magnitude and not direction. It may be viewed as analogous to height : just as a released object will fall through a difference in heights caused by a gravitational field, so a charge will 'fall' across the voltage caused by an electric field.
The equipotentials cross all lines of force at right angles. They must also lie parallel to a conductor 's surface, otherwise this would produce a force that will move the charge carriers to even the potential of the surface.
The electric field was formally defined as the force exerted per unit charge, but the concept of potential allows for a more useful and equivalent definition: the electric field is the local gradient of the electric potential.
Moreover, the interaction seemed different from gravitational and electrostatic forces, the two forces of nature then known. The force on the compass needle did not direct it to or away from the current-carrying wire, but acted at right angles to it.
This relationship between magnetic fields and currents is extremely important, for it led to Michael Faraday's invention of the electric motor in Faraday's homopolar motor consisted of a permanent magnet sitting in a pool of mercury.
A current was allowed through a wire suspended from a pivot above the magnet and dipped into the mercury. The magnet exerted a tangential force on the wire, making it circle around the magnet for as long as the current was maintained.
Experimentation by Faraday in revealed that a wire moving perpendicular to a magnetic field developed a potential difference between its ends.
Further analysis of this process, known as electromagnetic induction , enabled him to state the principle, now known as Faraday's law of induction , that the potential difference induced in a closed circuit is proportional to the rate of change of magnetic flux through the loop.
Exploitation of this discovery enabled him to invent the first electrical generator in , in which he converted the mechanical energy of a rotating copper disc to electrical energy.
The ability of chemical reactions to produce electricity, and conversely the ability of electricity to drive chemical reactions has a wide array of uses.
Electrochemistry has always been an important part of electricity. From the initial invention of the Voltaic pile, electrochemical cells have evolved into the many different types of batteries, electroplating and electrolysis cells.
Aluminium is produced in vast quantities this way, and many portable devices are electrically powered using rechargeable cells.
An electric circuit is an interconnection of electric components such that electric charge is made to flow along a closed path a circuit , usually to perform some useful task.
The components in an electric circuit can take many forms, which can include elements such as resistors , capacitors , switches , transformers and electronics.
Electronic circuits contain active components , usually semiconductors , and typically exhibit non-linear behaviour, requiring complex analysis.
The simplest electric components are those that are termed passive and linear : while they may temporarily store energy, they contain no sources of it, and exhibit linear responses to stimuli.
The resistor is perhaps the simplest of passive circuit elements: as its name suggests, it resists the current through it, dissipating its energy as heat.
The resistance is a consequence of the motion of charge through a conductor: in metals, for example, resistance is primarily due to collisions between electrons and ions.
Ohm's law is a basic law of circuit theory , stating that the current passing through a resistance is directly proportional to the potential difference across it.
The resistance of most materials is relatively constant over a range of temperatures and currents; materials under these conditions are known as 'ohmic'.
The capacitor is a development of the Leyden jar and is a device that can store charge, and thereby storing electrical energy in the resulting field.
It consists of two conducting plates separated by a thin insulating dielectric layer; in practice, thin metal foils are coiled together, increasing the surface area per unit volume and therefore the capacitance.
The unit of capacitance is the farad , named after Michael Faraday , and given the symbol F : one farad is the capacitance that develops a potential difference of one volt when it stores a charge of one coulomb.
A capacitor connected to a voltage supply initially causes a current as it accumulates charge; this current will however decay in time as the capacitor fills, eventually falling to zero.
A capacitor will therefore not permit a steady state current, but instead blocks it. The inductor is a conductor, usually a coil of wire, that stores energy in a magnetic field in response to the current through it.
When the current changes, the magnetic field does too, inducing a voltage between the ends of the conductor. The induced voltage is proportional to the time rate of change of the current.
The constant of proportionality is termed the inductance. The unit of inductance is the henry , named after Joseph Henry , a contemporary of Faraday.
One henry is the inductance that will induce a potential difference of one volt if the current through it changes at a rate of one ampere per second.
The inductor's behaviour is in some regards converse to that of the capacitor: it will freely allow an unchanging current, but opposes a rapidly changing one.
Electric power is the rate at which electric energy is transferred by an electric circuit. The SI unit of power is the watt , one joule per second.
Electric power, like mechanical power , is the rate of doing work , measured in watts , and represented by the letter P. The term wattage is used colloquially to mean "electric power in watts.
Electricity generation is often done with electric generators , but can also be supplied by chemical sources such as electric batteries or by other means from a wide variety of sources of energy.
Electric power is generally supplied to businesses and homes by the electric power industry. Electricity is usually sold by the kilowatt hour 3.
Electric utilities measure power using electricity meters , which keep a running total of the electric energy delivered to a customer.
Unlike fossil fuels, electricity is a low entropy form of energy and can be converted into motion or many other forms of energy with high efficiency.
Electronics deals with electrical circuits that involve active electrical components such as vacuum tubes , transistors , diodes , optoelectronics , sensors and integrated circuits , and associated passive interconnection technologies.
The nonlinear behaviour of active components and their ability to control electron flows makes amplification of weak signals possible and electronics is widely used in information processing , telecommunications , and signal processing.
The ability of electronic devices to act as switches makes digital information processing possible. Interconnection technologies such as circuit boards , electronics packaging technology, and other varied forms of communication infrastructure complete circuit functionality and transform the mixed components into a regular working system.
Today, most electronic devices use semiconductor components to perform electron control. The study of semiconductor devices and related technology is considered a branch of solid state physics , whereas the design and construction of electronic circuits to solve practical problems come under electronics engineering.
Thus, when either field is changing in time, then a field of the other is necessarily induced. Electromagnetic waves were analysed theoretically by James Clerk Maxwell in Maxwell developed a set of equations that could unambiguously describe the interrelationship between electric field, magnetic field, electric charge, and electric current.
He could moreover prove that such a wave would necessarily travel at the speed of light , and thus light itself was a form of electromagnetic radiation.
