AC generator
An AC generator is a device that produces alternating current by rotating a coil in a magnetic field.
Alternating current (AC)
An electric current that repeatedly changes direction, typically produced by a generator.
Direct current (DC)
An electric current that flows in one direction only, typically produced by a constant voltage source such as a battery.
Electric current
Electric current is the flow of electric charge through a conductor.
Electromagnetic induction
The production of a voltage in a conductor when it experiences a changing magnetic field (or when it moves through a magnetic field).
Transformer
A transformer is a device that changes the voltage of an alternating current (AC) using the principles of electromagnetic induction.
