100
a region around a charged particle or object within which a force would be exerted on other charged particles or objects.


What is an Electric Field?

100
a region around a magnetic material or a moving electric charge within which the force of magnetism acts.


What is a Magnetic Field ?

100

a portion of a ferromagnetic material where the magnetic moments are aligned with one another because of interactions between molecules or atoms.

What is a Magnetic Domain? 

100
each of the points near the extremities of the axis of rotation of the earth or another celestial body where a magnetic needle dips vertically.

What is a Magnetic Poles?

100

an electric current flowing in one direction only.

What is a Direct Current?

200
an electric current that reverses its direction many times a second at regular intervals, typically used in power supplies.

What is an Alternating Current? 

200
a soft metal core made into a magnet by the passage of electric current through a coil surrounding it.


What is an Electromagnet ?

200

the induction of an electromotive force by the motion of a conductor across a magnetic field or by a change in magnetic flux in a magnetic field.

What is an Electromagnet Induction ?

200

an apparatus for reducing or increasing the voltage of an alternating current.

What is a Transformers ?

200

is that value of resistance, which when replaced in place of the combination, will continue to give the same performance for the part of circuit outside this combination.

What is an Equivalent Resistance ?

300

a dynamo or similar machine for converting mechanical energy into electricity.

What is a Generator ?

300

a machine, especially one powered by electricity or internal combustion, that supplies motive power for a vehicle or for some other device with moving parts.

What is a Motor ?

300
the difference of electrical potential between two points.

What is a Potential Difference ?

300

is a material whose internal electric charges do not flow freely; very little electric current will flow through it under the influence of an electric field.

What is an Insulator ?

300

is an object or type of material that allows the flow of charge in one or more directions.

What is a Conductor ?
400

a device having a designed resistance to the passage of an electric current.

What is a Resistor ?

400

an electromotive force or potential difference expressed in volts.

What is Voltage ?

400

is the rate, per unit time, at which electricalenergy is transferred by an electric circuit.

What is Power ?

400
a unit of electric current equal to a flow of one coulomb per second.


What is an Ampere ?

400
the SI unit of electrical resistance, expressing the resistance in a circuit transmitting a current of one ampere when subjected to a potential difference of one volt.


What is an Ohm ?

500
the SI unit of electromotive force, the difference of potential that would drive one ampere of current against one ohm resistance.


What is a Volt ?

500

the process by which an electrical conductor becomes electrified when near a charged body, by which a magnetizable body becomes magnetized when in a magnetic field or in the magnetic flux set up by a magnetomotive force, or by which an electromotive force is produced in a circuit by varying the magnetic field linked with the circuit.

What is an Induction ?

500

is a closed circuit in which the current divides into two or more paths before recombining to complete the circuit.

What is a Parallel Circuit ?

500

is a closed circuit in which the current follows one path, as opposed to a parallel circuit where the circuit is divided into two or more paths.

What is a Series Circuit ?
