Theory

To calculate transformer efficiency, you need to use the formula: efficiency = (output power / input power) x 100%. The transformer's efficiency is impacted by both core losses (hysteresis and eddy current losses) and copper losses. The conditions for maximum efficiency occur when the copper losses equal the core losses.
