Answer:

Unit of power is J/s

So option (b) is correct option

Explanation:

We have given that Si unit of power is watt

We know that power is rate doing work

Sop power is given by [tex]Power=\frac{Energy}{time}[/tex]

Now we know that Si unit of energy is Joul and Si unit of time is sec

As power is ratio of energy and time

So its unit will be also the ratio of unit of energy and time

So the ratio of power will be J/s

So option (b) is correct option
