Define electric power and its formula.

The formula for electric power is:

Electric Power (P) = Voltage (V) ร Current (I)

Where:

Electric Power (P) is measured in watts (W).

Voltage (V) is the potential difference or electrical pressure measured in volts (V).

Current (I) is the flow of electric charge measured in amperes (A).

Mathematically, the product of voltage and current gives the power consumed or produced in an electrical circuit. This formula is known as Joule's law, named after James Prescott Joule, a British physicist who made significant contributions to the study of energy and heat in the mid-19th century.
