Question

In a dc 2 wire Feeder voltage drop per wire is 5% Transmission Efficiency of feeder is

Answer 1

The efficiency will be 90 percent.

Explanation:  

When the load is connected then both wires become in series. So, voltage drop across each wire will add up to give total voltage drop. As per wire voltage drop is 5% so total voltage drop will be 10%.

Hence, 100% - 10% = 90% voltage will reach at the load end.
