Answer
W (`watts`)
Explanation
The unit of power is calculated by multiplying potential difference with the current. The potential difference unit is volt (V) and the current is measured in amperes (A). According to the principle of power in Physics, when these two measurements are multiplied, the result will be in watts (W).
