Power
A region of magnetic influence around a magnetic pole or a moving charged particle
Magnetic field
A flow of electric charge that regularly reverses its direction.
Alternating current
Electromagnetic induction is the production of an electromotive force across a conductor exposed to time varying magnetic field
Electromagnetic induction

Resistance
A circuit with several current paths, whose total current equals the sum of the currents in its branches
Parallel circuit
A material through which electric charge can flow easily.
what is a Conductor
This is a unit of electrical resistance
Ohm
