An electric motor converts:
Correct answer: A. Electric energy to mechanical energy
- A. Electric energy to mechanical energy
- B. Mechanical energy to electric energy
- C. Mechanical energy to potential energy
- D. Not enough information
Explanation
An electric motor transforms electrical energy into mechanical energy.Motors consist of loops of wire in a magnetic field. When current is passed through the loops, the magnetic field exerts a torque on the loops, which rotates a shaft. Electrical energy is converted to mechanical work in the process.OPTIONS B, C & D are incorrect

About Electromagnetic Induction
Changing magnetic flux induces an emf according to Faraday's law, while Lenz's law gives the direction that opposes the change producing it. Transformers apply induction between coils to step alternating voltage up or down, with turns ratio, current transformation and energy losses determining practical operation.
