Voltage Drop Calculator.

This voltage drop calculator is a simple tool that helps you determine what voltage is lost when electric current moves through a wire.

Whether you're designing a low-voltage system, sizing a cable for a power installation, or checking if your wiring is efficient, this tool gives you quick and accurate results.

Our cable voltage drop calculator works by taking four essential parameters:

The material of the conductor (copper or aluminum), The wire length, The wire diameter or cross-section, And the current (intensity) flowing through the cable. With these inputs, the tool instantly calculates the voltage drop, helping you choose the right cable for safe and efficient performance.

For electronics projects, it can even be used as a voltage drop resistor calculator, giving you a clear idea of how much tension is lost due to resistance.

Accurate voltage drop estimation is crucial to avoid overheating, energy waste, and malfunctioning equipment. This calculator simplifies the process and ensures your electrical installations remain reliable and compliant.
