About Voltage Divider
A voltage divider is an essential electronic circuit used to reduce voltage from a source using two resistors. It is widely used in sensors, signal conditioning, and electronics projects.
How to Use?
- Enter the input voltage (Vin).
- Enter the resistor values R1 and R2 in ohms.
- Click "Calculate Vout" to find the output voltage.
- The output voltage is given by Vout = Vin × R2 / (R1 + R2).
