# Resistor Voltage Clculator

Introduction

Calculating resistor voltage in an electronic circuit is crucial for understanding the behavior and performance of components. To simplify this process, we can utilize a resistor voltage calculator. This tool enables engineers, hobbyists, and students to swiftly determine the voltage across a resistor based on Ohm’s Law.

## How to Use

- Input the value of the resistor in ohms (Ω).
- Enter the current flowing through the resistor in amperes (A).
- Click on the “Calculate” button to obtain the voltage across the resistor.

## Formula

According to Ohm’s Law, the formula to calculate voltage (V) across a resistor is:

*V*=*I*×*R*

Where:

*V*= Voltage across the resistor (volts)*I*= Current flowing through the resistor (amperes)*R*= Resistance of the resistor (ohms)

## Example Solve

Let’s consider a scenario where a resistor with a resistance of 100 ohms (Ω) experiences a current of 0.5 amperes (A). Using the formula: *V*=*I*×*R*

*V*=0.5×100

*V*=50 volts

So, the voltage across the resistor is 50 volts.
