Question

Power spent by a body depends on the time for which it does work.

• A. True
• B. False

Answer 1

The correct option is A

True

Power is defined as the rate of work done or energy spent. It is given by

$P=\frac{W}{t}$,
where P is the power spent, W is the work done and 't' is the time for which the work is done

Power spent by a source depends upon the time for which work is done. Power spent is greater if the same work is done in lesser time.
