Question

An electric fans has an electric motors inside to change:

• A. mechanical energy into electrical energy
• B. thermal energy into electrical energy
• C. electrical energy into thermal energy
• D. electrical energy into mechanical energy

Answer 1

Answer: (D)

electrical energy into mechanical energy

An electric motor converts electrical energy into mechanical energy. The armature in the motor, which has current passing through it, experiences a continuous torque placed in an external magnetic field. Hence the electrical energy provided is converted to mechanical(rotation) energy.
