Voltage Divider

                                           

                A voltage divider consists of two resistances R1 and R2 connected in series across. The supply voltage is divided between the two resistances to give an output voltage Vout which is the voltage across Resistor (R2).
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),
