Voltage Divider Calculator

The wiper cuts the resistor in two and moves it adjusting the ratio between the top half and the bottom half of the resistor.

Two resistor voltage divider calculator. A voltage divider circuit is a very common circuit used in electronics and consists of two resistors connected to step down the supply voltage in the circuit. The amount the supply voltage is scaled down is determined by the ratio of the resistor values to. Calculates the voltage drops on each resistor load when connected in series.

Sometimes we need a resistor value more precice than what is offered in the standard series. Resistor value and ratio calculator. R 2 is the resistance of the 2nd resistor measured in ohms w.

The four variables involved in a two resistor voltage divider are input voltage output voltage resistance 1 and resistance 2. The ratio of the resistors divides and input voltage down to a lower voltage. This calculator simplifies the task.

A voltage divider also known as a potential divider consists of two resistances r a and r b connected in series across a supply voltage v inthe supply voltage is divided between the two resistances to give an output voltage v out which is the voltage across r b. Alternatively you can also use this voltage divider calculator to provide any 3 known values in the circuit and calculate the 4th one. How it works is the ratio of the resistors r1 and r2 divides the input voltage down to a lower output voltage.

It is often the first circuit a beginner learns. Enter total voltage supply and press the calculate button. A voltage divider turns a large voltage into a smaller one.

Connect the two external pins to a voltage input and a reference ground with the middle wiper pin as your output pin and you have yourself a voltage divider. This is often done to set the division ratio in a voltage divider for example. One of the most basic and common circuits is the two resistor voltage divider.

The ratio of the two resistors used determines the amount that the voltage is reduced. Voltage divider circuit schematic. The two resistor voltage divider is one of the most basic and common circuits in electronics.

You can use this voltage divider calculator to determine any one of the four variables associated with a simple two resistor voltage divider when the values of the other three variables are available. R1 is the resistance of the 1st resistor r2 is the resistance of the 2nd resistor v out is the output voltage. A more complicated task is to pick resistors to satisfy a ratio.

For this task use the resistor value calculator. V s is the source voltage measured in volts v r 1 is the resistance of the 1st resistor measured in ohms w.
