Question

Write SI unit of power.

Answer 1

P= w/t

SI unit of work is joule and time is second. Therefore, SI unit of power is joule/second.

1 joule/second = 1 watt

If one joule of work is done in one second by any agent then its power is said to be one watt.

Kilowatt and megawatt are higher units of power.

1 kilowatt(kW)=10³ watts

1 Megawatt(MW)=10⁶ watts

Another unit of power is horse power.

1 horse power = 746 watts
