Voltage Drop Explained

14-08-2022 · Voltage drop (VD) occurs when the voltage at the end of a run of cable is lower than at the beginning. Any length or size of wires will have some resistance, and running a current through this dc resistance will cause the voltage to drop. As the length of the cable increases, so does its resistance and reactance increase in proportion.
