Explanation
## Step1: The problem can be solved using the formula for power in an electrical circuit, which is given by the product of the potential difference (or voltage) and the current. This is represented mathematically as
, where
is the power,
is the potential difference, and
is the current.## Step2: We are given the potential difference and the current, and we are asked to calculate the power. The potential difference is given as
V, and the current is given as
A. ## Step3: We substitute these values into the power formula to calculate the power. ###
