An electric generator works on the principle of
Aelectromagnetic induction
Bheating effect of current
Cchemical effect of current
DOhm's law
Answer & Solution
Correct answer: A. electromagnetic induction
1. Moving a coil in a magnetic field (or a changing field) induces a current in the coil.
2. This principle is **electromagnetic induction** (discovered by Faraday).
3. A generator uses it to convert mechanical energy into electrical energy.
