400 V rated 5 SCRs are connected in series. The operation voltage of the string is 500. Calculate the string efficiency.

400 V rated 5 SCRs are connected in series. The operation voltage of the string is 500. Calculate the string efficiency. Correct Answer 25 %

The string efficiency can be calculated using the formula operation voltage÷(Number of SCRs×Rated voltage) = 500÷(400×5) = 25 %.
