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
