What type of circuit is used as a voltage divider?

series resistor circuit
A voltage divider is a simple series resistor circuit. It’s output voltage is a fixed fraction of its input voltage. The divide-down ratio is determined by two resistors. Written by Willy McAllister.

How do potential dividers work?

A potential divider is a simple circuit which takes advantage of the way voltages drop across resistors in series. The amount by which the voltage drops over across each resistor depends on the relative values of each resistor and the total resistance.

How do you select a voltage divider resistor?

Choosing a resistor value The value of the resistor R determines the range (maximum and minimum values) of the output voltage Vo. For best results you need Vo to have a large range and this is achieved if R is much larger than the sensor’s minimum resistance but much smaller than its maximum resistance.

How do you use voltage divider bias?

One way to bias a BJT transistor is a method called voltage divider bias. This voltage divider configuration is the most widely used transistor biasing method, as the emitter diode of the transistor is forward biased by the voltage dropped across resistor RB2.

What are some examples of voltage divider schematics?

Examples of voltage divider schematics. Shorthand, longhand, resistors at same/different angles, etc. We’ll call the resistor closest to the input voltage (V in) R 1, and the resistor closest to ground R 2.

How do you evaluate a voltage dividing circuit?

There are a few generalizations that are good to keep in mind when using voltage dividers. These are simplifications that make evaluating a voltage dividing circuit just a little easier. First, if R2 and R1 are equal then the output voltage is half that of the input. This is true regardless of the resistors’ values.

What is input voltage divider circuit?

Input voltage is scaled down to by a fixed ratio determined by the resistor values. This is where the circuit gets its nickname: voltage divider. We want to find using the voltage divider relationship.

What is the scaling factor for the voltage divider formula?

From the above equation of the Voltage Divider formula, we can confirm that the scaling factor for the output voltage is determined by the ratio R2 / (R1 + R2). The basis for the voltage divider circuit is the Ohm’s Law.
