Circuit efficiency refers to the ratio of useful power output from a circuit to the total power input, often expressed as a percentage. A higher efficiency indicates that more of the input power is being converted into useful work, while lower efficiency signifies greater energy losses, primarily due to heat dissipation or other forms of energy dissipation. Understanding circuit efficiency is crucial in optimizing power calculations and improving overall system performance.
