To calculate the voltage drop, input the current, length, material, AWG, and type of circuit. The calculator will use the appropriate formula to determine the voltage drop.

For AC Single-phase and DC circuits:

$$ V_{drop} = \frac{2 \times I \times \rho \times L}{A} $$

For Three-phase circuits:

$$ V_{drop} = \frac{\sqrt{3} \times I \times \rho \times L}{A} $$
