If a 240 VAC motor pulls 10A with a 3% line drop, then what is the resistance of each wire feeding the motor?

Question

If a 240 VAC motor pulls 10A with a 3% line drop, then what is the resistance of each wire feeding the motor?

Answer 1

3 percent of 240 volts is 7.2v

R = E/I = 7.2/10 = 0.72 ohms.

But there are two wires, so the resistance is 0.36 ohms each.

.

Answer 2

    240V

    -------   =  24 OHMS X 3% = 0.72 OHMS X 1/2 = 0.36 OHMS per wire

      10A
