Question

Which of the following is/are the correct answer(s) ?

• A. The AC generator works on the principle of electromagnetic induction.
• B. Purpose of slip rings is to allow for electrical contact with the brushes.
• C. Electric generator converts mechanical energy into electrical energy.
• D. The AC generator works on the principle of Coulomb's law.

Answer 1

Answer: (A), (B), (C)

Electric generator converts mechanical energy into electrical energy.

The following statements are correct regarding an AC generator :

$1.)$ An AC generator works on the principle of electromagnetic induction.

$2.)$ Slip rings are two hollow rings to which two ends of the armature coil are connected. These rings rotate with the rotation of the coil. Its purpose is to allow for electrical contact with the brushes.

$3.)$ Electric generator converts mechanical energy into electrical energy.

Hence, options $\left(\text{A}\right),\left(\text{B}\right)$ and $\left(\text{C}\right)$ are the correct answers.
