Voltage Drop Calculator for Wires
Use this calculator to determine the voltage drop in electrical wiring based on wire gauge, run length, and current. This helps prevent energy losses and voltage issues in your circuits.
What this calculator is doing?
This calculator estimates the voltage drop across a length of wire carrying a specified load current. The voltage drop is computed using the formula: \[ V_{\text{drop}} = I \times R_{\text{total}} \] where: - \( I \) is the load current (A). - \( R_{\text{total}} \) is the total resistance of the wire run, calculated from wire gauge and total round-trip distance (twice the one-way length). Wire resistance values are based on standard American Wire Gauge (AWG) resistance per 1000 feet. The formula used is: \[ R_{\text{total}} = \text{Resistance per 1000 ft} \times \frac{\text{Length (ft)} \times 2}{1000} \] This helps you select the right wire gauge to minimize voltage losses and improve electrical system performance.
