Voltage Divider Calculator

Vin: Volts
Ra: Ohms
Rb: Ohms
Vout: Volts

The Voltage Divider Calculator to find the Vin, Ra, Rb, Vout, when you enter three values then will get the last one.

Voltage Divider Formula:

Vout = R2/(R1+R2) × Vin

Where Vin is Input Voltage, Vout is Output Voltage

For example, when Vin is 4 Volts, Rb is 2 Ohms, Vout is 1 Volts, then the Ra will be 6 Ohms.
