Is there a voltage drop on DC?
Voltage drop exists in both the supply and return wires of a circuit. In a DC circuit, voltage equals current multiplied by resistance. V = I R. Also, Kirchhoff’s circuit laws state that in any DC circuit, the sum of the voltage drops across each component of the circuit is equal to the supply voltage.
How much does DC voltage drop over distance?

What wire do I use for 24V?
If you have a 24V supply for a 200 amp device, we will assume that the wiring is copper and has a typical insulation and installation type. With a wire distance of 25 feet and a voltage drop of 3%, you will need a wire size of 4/0 AWG.
Why does DC voltage drop?
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.
How do you calculate dc voltage drop?
Use a voltage drop formula to assist you to manually calculate voltage drop in cables
- DC / single phase calculation.
- = Iwire (A) × (2 × L(ft) × Rwire(Ω/kft) / 1000(ft/kft))
- = Iwire (A) × (2 × L(m) × Rwire (Ω/km) / 1000(m/km))
- 3 phase calculation.
- = 1.732 × Iwire (A) × (L(ft) × Rwire (Ω/kft) / 1000(ft/kft))
Is voltage drop the same for AC and dc?
It’s actually the opposite. DC has a lower loss over a long distance. The reason for that is that AC has inductive losses over the distance, while DC does not. AC is used for high power transmission over moderate distances because it’s really, really easy to convert the voltage from high to low using transformers.
