A voltage divider circuit is a basic circuit that uses a pair of resistors to convert a higher voltage to a lower voltage. With 2 resistors R1 and R2, you may determine the voltage drop using our online voltage divider calculator.

If you are new to the concept of voltage dividers, we recommend reading our “Voltage Divider: A Comprehensive Guide“.

Voltage Divider Formula

The output voltage formula is presented below and is based on Ohms Law.

V(out)=V(in)*R2/R1+R2

where

  • V(in): The input voltage, V(in), is measured in Volts (V)
  • R1: is the first resistor’s resistance, measured in Ohms (Ω). Kilo Ohms (kΩ) or mega Ohms (mΩ) can be used.
  • R2: is the second resistor’s resistance, measured in Ohms (Ω). Kilo Ohms (kΩ) or mega Ohms (mΩ) can be used.
  • V(out): The output voltage, V(out), is measured in Volts (V)

Voltage Divider Example

To go over the concepts in greater depth. Let’s have a look at an example. If the input voltage is 230 volts, choose R1 and R2 as 5Ω. The output voltage is 115 volts.
