Question

An ac generator converts

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

Hint:

AC generators convert mechanical energy into electrical energy by rotating coils in a magnetic field, leading to an induced current.

Answer 1

The Correct Option is D

An alternating current (ac) generator works on the principle of electromagnetic induction. It converts mechanical energy into electrical energy. The mechanical energy comes from a rotating coil in the generator that moves within a magnetic field, and as the coil rotates, it induces an electromotive force (emf), thereby generating electrical energy. Thus, the correct answer is \( \boxed{\text{mechanical energy into electrical energy}} \).
