Using simplifications you can make it easier to evaluate a voltage divider circuit quickly. For this guide, however, we will only walk you through the one below. There are a few simplifications we can make to the voltage divider equation. The result of this multiplication will give you your Vout amount. Replace the division part of your formula with the value you have gotten, your equation should now look like what we have below.įinally, we can just multiply the Vin with our calculated resistor division amount. Using a calculator this will give us 0.7555555555555556, but for simplicity we will round this to 2 decimal places, meaning the number will become 0.76. In our example, this will be 680 divided by 900.

Just divide your R2 value with your calculated R1 + R2 value. Now that we have done the simple addition we can finally calculate the division part of the voltage divider equation. We will replace 220 + 680 in our formula with our result, so that we end up with the following equation. So in our example above, this will end up being 220 + 680, which is equal to 900.

To begin with, we will first plus the R1 and the R2 resistor values together. Now if we plug these values into our voltage divider equation, we should end up with something like what we have displayed below. Volts (V) Voltage Divider Formula Examplesįor our first example of utilizing the Voltage Divider formula we are going to utilize the following values: If you want to quickly calculate the output voltage generated by your voltage divider circuit then you can make use of our handy calculator.Īll you need to do is enter the values for your two resistors and the input voltage, the calculator will automatically work out the corresponding output voltage.

Vout is the output voltage measured in volts ( V).

R2 is resistance of the 2nd resistor in the voltage divider, measured in Ohms Ω.

R1 is resistance of the 1st resistor in the voltage divider, measured in Ohms Ω.

Vin is the input voltage measured in volts ( V).

We will now go over the variables used in the voltage divider equation one final time so that you will have a solid understanding of each variable. Utilizing these three values in the equation below will allow us to calculate the output voltage of a voltage divider circuit. You will need to know both the resistor values ( R1 and R2) and also the input voltage ( Vin). The values that you will need to know to make use of the equation are the following three. The voltage divider equation assumes that you know three of the values utilized in the circuit. We use R1, R2, Vin, and Vout to name elements of the circuit as they are crucial to understanding the values you will need for the voltage divider equation. This divided voltage is a fraction of the original input voltage ( Vin). The resulting voltage drop is what we will be referring to as our divided voltage. The voltage drop that is caused by the input voltage going through the resistor pair ( R1 and R2) is referred to as Vout.

The resistor that is closest to the ground connection is typically referred to as R2. One resistor should be connected to ground, the other to a source voltage and a wire coming from in between the pair with the output voltage.Īs you can see in a basic setup of the voltage divider circuit the resistor that is closest to the input voltage ( Vin) will usually be referred to as R1. The circuits should consist of two resistors. Basic Voltage Divider Circuitīelow are some examples of how you could see a voltage divider circuit setup or drawn.Īll voltage divider circuits should look fairly similar. The second resistor is typically connected to ground. The input voltage is applied across the two resistors with your desired output voltage coming from the connection between the two resistors.

In basic terms, a voltage divider transforms a large voltage down into a smaller one.Ī basic voltage divider circuit consists of two resistors wired in series that produces an output voltage that is just a fraction of its input voltage. In this guide, we will be exploring a very crucial and fundamental element in electronic circuits, and that is voltage dividers.Ī voltage divider is a somewhat basic passive circuit that plays a very crucial role.
