Question

What energy conversion does take place in a generator when it is in use?

• A. The electrical energy changes into the electrical energy.
• B. The mechanical energy changes into the mechanical energy.
• C. The electrical energy changes into the mechanical energy.
• D. The mechanical energy changes into the electrical energy.

Answer 1

The correct option is D The mechanical energy changes into the electrical energy.

The generation of electrical power requires relative motion between a magnetic field and a conductor. In a generator, mechanical energy is converted into electrical energy. The electricity produced by most generators is in the form of alternating current.
