What is the Voltage Drop In Circuit Calculator?

The Voltage Drop In Circuit Calculator computes the voltage drop across a wire in an electrical circuit based on current, resistance, and wire length. This tool is valuable for electricians, engineers, and students to ensure proper circuit design, prevent power loss, and maintain safe and efficient electrical systems. It provides fast and accurate results for planning and troubleshooting circuits.

How to Use:

1. Enter Current (I): Type the current in amperes flowing through the circuit.
2. Enter Resistance (R): Input the resistance of the wire in ohms.
3. Enter Length of Wire (L): Specify the length of the wire in meters.
4. Click “Calculate”: The calculator computes the voltage drop using the formula V = I × R × L.
5. Review the Result: Use the voltage drop value to design circuits, check safety limits, or minimize energy loss.
