|That force which is generated to cause current to flow in an electrical circuit. It is also referred to as electromotive force or electrical potential. It is measured in volts.
|the practical meter-kilogram-second unit of electric resistance equal to the resistance of a circuit in which a potential difference of one volt produces a current of one ampere
|A device usually made of wire or carbon which presents a resistance to current flow.
|states that when an electric current is flowing through a conductor, such as a wire, the intensity of the current equals the electromotive force driving it, divided by the resistance of the conductor.
|A unit of measure for indicating the electrical power applied in a circuit.
|electric current can flow freely
|A circuit in which the circuit components are arranged in branches so that there is a separate path to each unit along which electrical current can flow.
|the SI unit of electric charge, equal to the quantity of electricity conveyed in one second by a current of one ampere.
|a unit of frequency equal to one cycle per second
|A device constructed of semi - conductors that is used in circuits to control a larger current by using a smaller current for operation.
|The opposing or retarding force offered by a circuit or component of a circuit to the passage of electrical current through it. It is measured in ohms.
|an electric current which periodically reverses direction
|an electrical current that flows only in one direction.
|an electrical conductor placed in the ground or earth to protect consumers from unfortunate electrical shocks and to provide return path for electrical current
|A substance or body that resists the flow of electrical current through it.
|the unit of energy
|A device which stores electrical energy. Commonly used for filtering out voltage spikes.
|A device of electronic components used to increase power, voltage, or current of a signal.
|A circuit in which the parts are connected end to end, positive pole to negative pole, so that only one path is provided for current flow.
|a path in which electrons from a voltage or current source flow
