the total resistance of 2 12 AWG conductors 75 ft long is 03

the total resistance of 2 12 AWG conductors, 75 ft long is 0.3 ohms, and the current through the circuit is 16A. What is the power loss of the conductors

Solution

Resistance of one conductor=0.3/2=0.15 ohms

power loss of one conductor= (i^2)×resistance of one wire=16×16×0.15=38.4 watts

Total power loss= 38.4+38.4=76.8 watts
