Voltage drop over distance calculator
One of the easiest ways to calculate voltage drop is to use an online voltage drop calculator. Length of the run should only account for distance between the source and the load.
This calculator also calculates the voltage drop and the resulting voltage.
. Distance One-Way ft Load Amperes Conductor Size. Xc is the wire reactance in Ωkm or Ω1000ft. Voltage Drop Calculator Calculate Your Voltage Drop Determines wire size to meet specific voltage drop limits or calculates voltage drop for a specific conductor run.
At first we calculate the current through the circuit using I V R. The voltage drop V in volts V is equal to the wire current I in amps A times 2 times one-way wire length L in feet ft times the wire resistance per 1000 feet R in ohms Ωkft divided by. I 5 250 2 25 5 255 001961 A 1961 mA.
