When work is measured in joules and time is measured in seconds, power is measured in

Watts

Explanation:

Work done of an object is given by the product of force and displacement i.e.

W = F.d

Where

F = force

d = displacement

The SI unit of work done is joules. It is defined as the amount of energy used or exerted when a force of 1 newton is applied over a distance of 1 meter.

Power output is defined as "work done per unit time". Mathematically, it is given by :

The SI unit of power is watts. It is defined as the "amount of energy used when 1 joule of work is done per unit time".

Hence, power is measured in watts.
