Question

Determine the voltage drop on a branch circuit given the following related information:

current = 5 amperes
conductor length = 300 ft.
conductor resistance = 4 ohms per 1,000 feet

TheoryPractice · Accepted Answer

6 volts. To determine the voltage drop on this circuit, first find the resistance total with the information given in the question:

Resistance = 4 ohms ÷ 1000 ft. = .004 ohms per ft.

.004 ohms x 300 ft. = 1.2 ohms total resistance

Next, apply the voltage drop formula, VD = I X R:

VD= 5 amperes x 1.2 ohms = 6 volts dropped.
