Detailed Solution

Power is equal to

1 W

if any device consumes

1 J

of energy in

1 s

.
Power is defined as the rate of doing work.
The SI unit of power is Watt. 1 Watt is equal to 1 Joule work done in 1 second of time.

Power = \frac{Work}{Time}

= \frac{(Force \times Displacement)}{Time}

Its SI Unit is Watt.
Watt:- Watt is Joule Per Second.

P = \frac{E}{t}

P = \frac{W}{t}

Where

E

is The Energy Consumed to do work.

W

is the work done.

t

is the time taken.

P = \frac{W}{t}

\Rightarrow

Power is inversely proportional to time. Hence less time more the Power.
