An electric motor:

  1. A
    generates mechanical energy.
  2. B
    generates electric energy.
  3. C
    converts mechanical energy into electric energy.
  4. D
    converts electrical energy into mechanical energy.

Solution & Step-by-step Explanation

An electric motor functions on the principle of magnetic force on a current-carrying conductor (Lorentz force). It takes electrical energy as input and converts it into rotational mechanical energy output. Conversely, an electric generator converts mechanical energy into electrical energy.
