Voltage Drop Calculator(Single-Phase)

Voltage Drop Formula:

Single-Phase: Voltage Drop(VD)= 2× I× R× LConductor Wire Size(CM) 



Resistance(R)=12.9 for copper and 21.2 for Aluminum



Enter the unknown value as ' x '

Enter current(I)= Amp

Enter Length of Circuit(L)= m

Enter Conductor Wire Size(CM)= m

Enter Voltage Drop(VD)= V







x = (For Copper)
x = (For Aluminium)
