A very common application of a voltage divider circuit is to replace one of the fixed value resistors with a sensor.

Resistor voltage divider circuit. The most basic and commonly used voltage divider circuit is that of two fixed value series resistors but a potentiometer or rheostat can also be used for voltage division by simply adjusting its wiper position. The ratio is determined by two resistors. 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 output voltage is a fixed fraction of the input voltage. Voltage dividers are used in many applications but they are widely used in all types of variable resistors. Therefore voltage across r1 is 4v and voltage across r2 is 8v.

The formula for calculating the output voltage is based on ohms law and is shown below. Hence this is called voltage divider circuit. The divide down ratio is determined by two resistors.

R 1 is the resistance of the 1st resistor measured in ohms w. The circuit above shows a voltage divider circuit involving a 2kw and a 1kw resistor. If the voltage from the microcontroller is 5v then the leveled down voltage to the sensor is calculated as.
