Enter the current and the resistance into the calculator to determine the voltage loss in a circuit. This calculator helps in estimating the voltage drop across a component or section of a circuit.

## Voltage Loss Formula

The following formula is used to calculate the voltage loss.

V_{loss} = I * R

Variables:

- V
_{loss}is the voltage loss (volts) - I is the current (amperes)
- R is the resistance (ohms)

To calculate the voltage loss, multiply the current by the resistance.

## What is Voltage Loss?

Voltage loss, also known as voltage drop, refers to the reduction in voltage as electric current flows through the components and conductors of an electrical circuit. It is caused by the resistance or impedance of the conductive path. High voltage loss can lead to inefficient circuit operation and can be critical in long runs of cable or in circuits with high current flow. Understanding and calculating voltage loss is essential for designing effective electrical systems.

## How to Calculate Voltage Loss?

The following steps outline how to calculate the Voltage Loss.

- First, determine the current (I) flowing through the circuit in amperes.
- Next, determine the resistance (R) of the component or section of the circuit in ohms.
- Use the formula V
_{loss}= I * R to calculate the voltage loss. - Finally, enter the values into the calculator to verify the voltage loss.
