☑ Resistor Divider Voltage

The four variables involved in a two resistor voltage divider are input voltage output voltage resistance 1 and resistance 2. A simple example of a voltage divider is two resistors connected in series with the input voltage applied across the resistor pair and the output voltage emerging from the connection between them.

But by adding another resistor to the resistive sensors we can create a voltage divider.

Resistor divider voltage. R 1 is the resistance of the 1st resistor measured in ohms w. Thus r 1 4v and r 2 8v. In electronics a voltage divider is a passive linear circuit that produces an output voltage that is a fraction of its input voltage.

Voltage division is the result of distributing the input voltage among the components of the divider. 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 calculator also plots the circuit diagram and generates the component values.

Applying kirchhoffs voltage law shows that the sum of the voltage drops around the resistive circuit is exactly equal to the supply voltage as 4v 8v 12v. The voltage divider calculator calculates the output voltage of the voltage divider network based on the value of resistor r1 resistor r2 and the input voltage vin. Input the three known variables.

Once the output of the voltage divider is known we can go back and calculate the resistance of the sensor. How to use the voltage divider calculator. The formula for calculating the output voltage is based on ohms law and is shown below.

This output voltage which is the voltage that is dropped across resistor r2 is calculated by the formula vout vin r2r1 r1. Resistor voltage dividers are commonly used to create reference v. For example the photocells resistance varies between 1kw in the light and about 10kw in the dark.

Using the voltage divider ratio rule we can see that the largest resistor produces the largest ir voltage drop.
