Question

si unit of power give me answer
​

Answer 1

The S.I. unit of power is $watt$. James Watt was an inventor and mechanical engineer. He measured the power of a horse (standard one) by observing how much load it can pull within unit time. To honor him we take the name to use as unit of $power$.

Power, $P = W/t$

here, $W$ stands for $Work$ and $t$for $time$.

The amount of work by any system in unit time is called it's power.

The unit of work or energy is $joule$ (to honor James Prescott Joule) and unit of time is $second.$

So, 1 $joule$per second equal 1 $watt.$

Answer 2

Answer:

watt

The dimension of power is energy divided by time. In the International System of Units (SI), the unit of power is the watt (W), which is equal to one joule per second.
