Voltage drop of the circuit conductors can be determined by multiplying the current of the circuit by the total resistance of the circuit conductors: VD = I x R.

How to calculate voltage drop formula?
How do I calculate voltage drop? To calculate voltage drop use one of the three equations: V=R*I, if the flowing current and the electric element's resistance are known. V=P/I, if the power and electric current are known.
How to calculate the voltage drop across each load?
Now that we know the amperage for the circuit (remember the amperage does not change in a series circuit) we can calculate what the voltage drops across each resistor is using Ohm's Law (V = I x R).
What is the voltage drop per 100 feet?
To use the chart, we need to determine what the maximum voltage drop per 100 feet is. We calculate that 100 feet is 1/4 of 400 feet, thus the voltage drop allowed for 100 feet is 1/4 times 3 volts (which is the equivalent of 0.75 volts per 100 feet): voltage drop per 100 feet = 3/4 = . 75 volts per 100 feet.
What is the formula for voltage drop with K?
VD = 1.732 x K x Q x I x D/CM (3-phase), where “VD” = Volts Dropped: We express the voltage drop of the circuit conductors in volts. “K” = Direct Current Constant: This is a constant representing the direct current resistance for a 1000 circular mils conductor that's 1000 ft long, at an operating temperature of 75°C.
