Voltage Divider Calculator

What is a Voltage Divider Calculator?

A Voltage Divider Calculator is a tool used to determine the output voltage (Vout) of a simple voltage divider circuit. A voltage divider is an electrical circuit that reduces voltage using two resistors.

A voltage divider is a fundamental circuit in electronics, used to step down voltages for sensors, microcontrollers, and other components.

Why Use a Voltage Divider Calculator?

A Voltage Divider Calculator is useful for:

• Electronics Design – Helps engineers design circuits efficiently.
• Microcontrollers & Sensors – Used to reduce voltage for Arduino, Raspberry Pi, etc.
• Power Management – Determines correct voltages for different components.
• Circuit Debugging & Testing – Verifies voltage drops in circuits.

How to Use a Voltage Divider Calculator?

1. Enter Input Voltage (Vin) – The total voltage supplied to the circuit.
2. Enter Resistor Values (R1 & R2) – Choose values in ohms (Ω).
3. Click Calculate – The tool computes the output voltage (Vout).
4. Analyze the Output – Ensure the voltage suits your application.

When to Use a Voltage Divider Calculator?

Use this tool when:

• Reducing Voltage for Sensors – Many sensors require lower input voltage.
• Creating Reference Voltages – For ADC (analog-to-digital converter) circuits.
• Designing Power Circuits – Ensures components receive safe voltages.
• Debugging Electronics – Checks voltage distribution in circuits.
