What determines the rate at which energy is delivered by a current?

Solution

Power:
Electric power is the rate at which electrical energy is transferred by an electric circuit per unit of time.
The SI unit of power is $Watt (W)$ .
Power is denoted by P.
Mathematically, this can be represented as:
$P = VI$
Here,
V is the potential difference.
I is the electric current.
Therefore, electric power determines the rate at which energy is delivered by a current.
