In a series circuit, the currents on the resistors are equal, and the sum of the voltages across the resistors is equal to the total voltage of the circuit. It can be seen that the voltage on each resistor is less than the total voltage of the circuit, so the series resistor is divided.

\(V_{in} = Input voltage\)

\(V_{out} = The output voltage\)

Formula:

Vout = [ Rb / (Ra+Rb) ] * Vin

Vin = Input Voltage

Vout = Output / Reference Voltage

Ra, Rb = Resistances
