![]() The required output voltage (Vout) can be obtained across the resistor R2. This circuit is very useful for all analog circuits where variable voltages are required, hence it is important to understand how this circuit works and how to calculate the values of Resistors.Ī voltage divider circuit is very simple circuit consisting of only two resistors (R1 and R2) as shown above. Input Voltage (V in):Ī potential divider circuit is a very common circuit used in electronics where an input voltage has to be converted to another voltage less than it. R2 is the resistance of the 2nd resistor,Īlternatively, you can also use this voltage divider calculator to provide any 3 known values in the circuit and calculate the 4th one.R1 is the resistance of the 1st resistor,.
