POWER is the rate at which energy is transferred or converted. In an electrical circuit, POWER is calculated as the product of POTENTIAL DIFFERENCE and CURRENT:
This formula tells you how much energy is used per second when a current flows through a component at a certain potential difference.
There's another way to calculate POWER if you know the RESISTANCE of a component and the CURRENT flowing through it:
This shows that POWER also depends on the square of the CURRENT and the RESISTANCE the current encounters.
