# Voltage Drop
> [!info] Ohm's Law

$$
Vd = \frac{ I \times R \times L \times M }{ P }

$$
L = \frac{ Vd }{ I \times M } \times \frac{ P }{ R }

where
- $Vd$ = Maximum Voltage Drop in volts
- $I$ = Current in Amps
- $R$ = Resistance in ohms per foot
- $L$ = Length of wire one way in feet
- $M$ = Multiplier
- $2$ for 1-phase
- $\sqrt{3}$ for 3-phase
- $P$ = Number of parallel runs
