Efficiency in electronic components refers to the ratio of useful output energy or power to the input energy or power. It is a measure of how effectively a component converts input energy into output energy without wasting any energy in the process. Higher efficiency indicates that the component is more effective in performing its intended function while minimizing energy losses. Efficiency is an important parameter in electronic components such as power supplies, amplifiers, and motors, as it directly impacts the overall performance and energy consumption of the system. Manufacturers often specify the efficiency rating of their components to help users understand how efficiently the component operates under different conditions.

Power in electronic components refers to the rate at which electrical energy is transferred or converted by a device. It is typically measured in watts and can be calculated using the formula Power equals voltage multiplied by current. In circuits, power can represent the energy consumed by devices such as resistors, or the energy output by sources like batteries. Understanding power is crucial for ensuring components operate within safe limits and for designing efficient electronic systems.
