The measure of energy consumed by a circuit is called __________.

The measure of energy consumed by a circuit is referred to as power. In the context of electrical circuits, power quantifies the rate at which energy is transferred or converted. It is measured in watts (W), which indicates how much energy is used per unit of time. In electrical systems, power can be calculated using the formula P = VI, where P is power, V is voltage, and I is current. This relationship highlights that power is directly related to both the voltage supplied to the circuit and the current flowing through it.

Understanding power is crucial in various applications, such as electrical engineering and circuit design, where the efficiency and performance of the circuit can be analyzed through power consumption. This term distinguishes itself from other related concepts like dissipation, which refers to energy lost as heat, and general notions of consumption or usage, which may not specifically indicate the rate of energy transfer in a defined manner.
