What is the measurement of electrical energy transfer per unit time known as?

The measurement of electrical energy transfer per unit time is known as power. Power quantifies how much energy is consumed or produced in a given time frame and is typically measured in watts (W).

In electrical circuits, power is can be calculated using the formula ( P = IV ), where ( P ) is power, ( I ) is the current in amperes, and ( V ) is the voltage in volts. This highlights its role in describing the rate at which electrical energy is converted into other forms of energy, such as heat, motion, or light.

Understanding power is crucial when analyzing electrical systems, as it determines how efficiently energy is being used and is fundamental in the design of electrical devices and systems. While current, energy, and voltage are all related concepts in electricity, they do not directly define the rate of energy transfer. Current refers to the flow of electric charge, energy represents the capacity to do work, and voltage represents the potential difference that drives current in a circuit.
