  • Efficiency of Transformer - your electrical guide

    The efficiency of transformer is defined as the ratio of output power to input power. It is denoted by ἠ. As the output power is always less than the input power due to losses in the transformer, practically the transformer efficiency is always between 0 and 1 i.e. 0% and 100% but it can never be 1 or 100%. The efficiency of an ideal transformer is equal to 1 or 100% since the losses in the ...
