Question

Power is ______

(a) Rate of doing work

(b) Ability to do work

(c) Rate of energy creation

(d) Equivalent to work

This question was posed to me in an internship interview.

I'd like to ask this question from Introduction to Work, Energy and Power in section Work, Energy and Power of Physics – Class 11

Answer 1

Correct choice is (a) Rate of doing work

To explain: Power is defined as the rate of doing work. The ability to do work is energy. Energy can neither be created nor be destroyed, hence, the rate of energy creation does not exist.
