Voltage Drop Calculations
For cables operating under dc conditions, the appropriate voltage drops may be calculated using the formula. 2 x route length x current x resistance x 10¯³.
How do you calculate voltage drop in a wiring harness?
By dividing the paired wire length by 100, we get the factor by which we need to multiply voltage drop per 100 feet to determine total voltage drop. Therefore, 350 feet divided by 100 equals 3.5. Multiply 3.5 by 1.27 volts drop per 100 feet to get your total voltage drop.

VD = R x I x L / 1000
Determine the voltage drop of a 380V, 3 phase circuit with a current of 100A and a length of 150 m and a conductor size of 35 mm. This is a secondary service feed. The voltage drop of secondary service is limited to 3% (380 x 3% = 11.4 Volts). Volt drop = Resistance x Current x Length / 1000.
What is the formula for finding the voltage drop?
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.
This free voltage drop calculator estimates the voltage drop of an electrical circuit based on the wire size, distance, and anticipated load current.
