(Blank)
A region around a charged particle or object within a force would be exerted on other charged particles or objects.
What is Electric field?
An electric current that reverses its direction many times a second at regular intervals, typically used in power supplies.
What is alternating current?
Any device for converting mechanical energy into electrical energy by electromagnetic induction especially a large one in a power station.
What is generator?
A passive electrical component with two terminals that are used for either limiting or regulating the flow of electric current in electrical circuits.
What is resistor?
A representation of the electric potential energy per unit charge.
What is volt?
A region around a magnetic material or moving electric charge within which the force of magnetism acts.
What is magnetic field?
A soft metal core made into a magnet by the passage of electric current through a coil surrounding it.
What is electromagnet?
A device which transforms the electrical energy into mechanical energy.
What is motor?
The difference in electric potential energy between two points per unit electric charge.
What is voltage?
magnetic field which is proportional to the rate of change of the magnetic field.
What is induction?
A region within a magnetic material in which the magnetization is in a uniform direction.
What is magnetic domain?
A current produced because of voltage production (electromotive force) due to a changing magnetic field.
What is electromagnetic induction?
The difference in potential between two points that represents the work involved or the energy released in the transfer of a unit quantity of electricity from one point to the other.
What is potential difference?
The rate at which work is done upon an object
What is power?
A circuit whose elements are connected through two points in common.
What is parallel circuit?
Each of the two points or regions of an artificial or natural magnet to and from which the lines of magnetic force are directed.
What is magnetic poles?
A device that can change the potential difference or voltage of an alternating current
A ___ increases the voltage.
A ______ reduces the voltage.
What is transformer?
What is step up transformer?
What is step down transformer?
Any material or device that insulates, especially a material with a very low electrical conductivity or thermal conductivity or something made of such a material.
What is insulator?
A measure of the amount of electric charge in motion per unit time
What is ampere?
A circuit with one loop, all electrons in that loop form one current.
What is series circuit?
An electric current flowing in one direction only.
What is direct current?
A point where the total resistance is measured in a parallel or series circuit (in either the whole circuit or in a part of the circuit).
What is Equivalent resistance?
A material or object that permits an electric current to flow easily.
What is conductor?
The SI derived unit used to measure the electrical resistance of a material or an electrical device.
What is ohms?
