What is Voltage Drop

Voltage drop is defined as the amount of voltage loss that occurs through all or part of a circuit due to impedance. A common analogy used to explain voltage, current and voltage drop is a garden hose. … This condition causes the load to work harder with less voltage pushing the current.

Voltage drop Formula for DC/Single Phase:

Vdrop = I*R

I – flow of current

R – resistance of the circuit

Resistance of the wire = Resistivity of the material* Length/Cross-section of the cable

Example Problem:

How far can No. 6 copper wire be used to carry a load of 30 amperes at 240 volts and keep within 1% voltage drop?
