How is electric power calculated?

Electric power is calculated using the formula Power (P) = Voltage (V) × Current (I). This relationship is fundamental in electrical systems, as it defines how power is derived from the flow of electric current through a circuit when a voltage is applied.

In this context, voltage represents the electric potential difference that drives the current through the circuit, while current is the flow of electric charge. When you multiply these two factors, you obtain power, which is measured in watts. This means that if you know both the voltage in a circuit and the current flowing through it, you can easily determine the electrical power being consumed or produced.

This formula is prevalent in various applications, from household appliances to industrial equipment, emphasizing the connection between voltage, current, and how much power is being used or generated in an electrical system.
