alleryAn electric motor converts:
AMechanical energy into electrical energy
BElectrical energy into mechanical (rotational) energy
CHeat energy into electrical energy
DElectrical energy into chemical energy
Answer & Solution
Correct answer: B. Electrical energy into mechanical (rotational) energy
1. A motor uses the FORCE on a current-carrying conductor in a magnetic field (F = BIL).
2. This force produces a TORQUE that rotates the coil.
3. Hence ELECTRICAL energy is converted into MECHANICAL (rotational) energy.
4. A GENERATOR (dynamo) does the reverse: mechanical → electrical via EMI.
