About this Calculator:

This DC Motor Voltage Drop Calculator helps you estimate the voltage drop across wires when powering a DC motor based on various inputs such as wire gauge, wire length, and motor current draw. By providing these inputs, you can ensure proper wire sizing to avoid performance issues due to voltage drop.

Equations Used:

Voltage Drop (V): \( V_{drop} = I \cdot R \)

Percentage Voltage Loss (%): \( \text{Loss} = \left( \frac{V_{drop}}{V_{supply}} \right) \cdot 100 \)
