Answer:
a) Generator
Step-by-step explanation:
Generator converts mechanical energy into electrical energy,
while motor converts electrical energy into mechanical energy.
Generator works because of electro magnetic induction which is when a voltage is induced due to changing magnetic field.
Transformer is a passive device that transfers electrical energy from one electrical circuit to another
Voltage is a electro motive force or the potential difference expressed in Volts
Current the rate at which charge is flowing
