Question

formula of efficiency of real transformers ?Agar dam h to answer do​

Answer 1

Explanation:

Transformers are the most highly

efficient electrical devices. Most of the transformer have full load efficiency between 95% to 98•5%. As a transformer being highly efficient, output and input are having nearly same value, and hence it is impractical to measure the efficiency of transformers by using output/ input. A better method to find efficiency of a transformer is using , efficiency = ( input - losses ) / input = 1 - ( losses / input ).
