Chapter 37, Problem 7A

What is a generator, and how does it differ from a motor?

To determine

To Explain: The term generator and its difference from the motor.

Answer to Problem 7A

A device that converts mechanical energy to an electrical energy, called generator. Generator works on the principle of Fleming’s right-hand rule and motor works on Fleming’s right-hand rule.

Explanation of Solution

Introduction: On the basis of working principle, functions, etc., motor and generator can be differentiated easily.

A generator is used to change mechanical energy into electrical energy. It works according to a law of electromagnetic induction.    

• Generator: It follows Fleming’s right-hand rule. It generates electricity.
• Motor: It follows Fleming’s left-hand rule.It uses electricity.

Conclusion: Working principle of generator and motor are different form each other.
