A voltage divider circuit is a very common circuit that takes a higher voltage and converts it to a lower one by using a pair of resistors. The formula for calculating the output voltage is based on Ohms Law and is shown below.
- VS is the source voltage, measured in volts (V),
- R1 is the resistance of the 1st resistor, measured in Ohms (Ω).
- R2 is the resistance of the 2nd resistor, measured in Ohms (Ω).
- Vout is the output voltage, measured in volts (V),
