A voltage divider circuit is a basic but important part of electronics. Whether you’re a student, hobbyist, or engineer, figuring out the output voltage (Vout) or resistor values can be tricky. Our Voltage Divider Calculator makes these tasks quick and easy!
How a Voltage Divider Works
A voltage divider uses two resistors (R1 and R2) connected to a power source (Vs). The output voltage (Vout) across R2 is calculated with this simple math formula:
Vout = (Vs × R₂) / (R₁ + R₂)
But sometimes you might need to find a missing resistor value or the input voltage. That’s where our Voltage Divider Calculator shines! Just plug in three known values, and it solves the fourth for you.
What Our Voltage Divider Calculator Can Do
- Find Vout: Enter Vs, R1, and R2 to get the output voltage.
- Find R2: If you know Vs, R1, and Vout, it calculates R2.
- Find R1: Type in Vs, R2, and Vout to get R1.
- Find Vs: Enter R1, R2, and Vout to find the input voltage.
