To calculate the efficiency of a single-phase transformer, use the formula: Efficiency (?) = (Output Power / Input Power) � 100%. First, measure the output power, which is the product of the secondary voltage and current. Then, determine the input power, which is the sum of the output power and losses (core and copper losses). Finally, substitute these values into the formula to find the efficiency percentage.
