Voltage Divider Formula
Voltage Divider Formula
It will output a portion of the input voltage. Usually, a voltage source, two resistors, and a resistor are used to create it. The resistors are linked together in series. And these two resistors are crossed by the voltage. It is referred to as a possible divider. We will discuss the Voltage Divider Formula with an example in this article.

Voltage Divider Formula
The series of resistors or capacitors known as a voltage divider can be tapped at any point in the middle to produce a particular percentage of the voltage applied between its ends.
It is made up of an electric circuit with two resistors and a single source of input voltage. A simple voltage divider has two resistors wired in series in a circuit. The voltage divider’s output voltage is dependent on its input voltage. This circuit aids in determining how the input voltage is distributed among the circuit’s parts.

What is the division of voltage in a circuit?
The resistors or other elements of the voltage divider circuit divide the input voltage. The voltage division occurs as a result. The voltage divider calculator can be used if we need assistance with the voltage division calculation.
A voltage divider is formally a straightforward circuit that divides a large voltage into two smaller ones. We can produce an output voltage that is only a small portion of the input voltage by using just two series resistors and the input voltage. One of the frequently used circuits in electronics is the voltage divider. Therefore, learning Ohm’s law can be compared to learning the circuit alphabets, and learning about voltage dividers can be compared to learning how to form words.
The formula for Voltage Divider
A voltage divider is a set of resistors or capacitors that can be tapped at any point in the middle to create a specific proportion of the voltage applied between its ends.
It consists of a single source of input voltage, two resistors, and an electrical circuit. Suppose an illustration that shows a straightforward voltage divider. In the circuit, two resistors are connected in series. The input voltage to the voltage divider affects its output voltage. Using this circuit, one can figure out how the input voltage is split up among the circuit’s components.
A voltage is being applied across a series of two resistors by a voltage divider. Although we may draw in a variety of ways, the circuit should always essentially be the same.
Thus, formula is given as follows:
V out=(Rb/Ra+Rb)×Vin
Where,
V out=Output Voltage
V in=Input Voltage
R a=Input Registor
R b=Output Registor
Voltage dividers have a wide range of uses, making them one of the most popular circuits used by electrical engineers. There are many applications. Potentiometers, reading resistive sensors, level shifting, etc. are a few examples.
Solved Examples on Voltage Divider
Q.1: Find out the output voltage of the voltage divider circuit whose two registers are 6ω and 8ω respectively and the input voltage is 20V. Where 8 ω is in parallel to the output voltage.
Solution:
Ra=6ω,
Rb=8ω
Vin=20V
Now, applying the Voltage divider formula,
Vout=RbRa+Rb×Vin
Substituting the known values,
Vout=86+8×20
= 814×20
= 807
Vout=11.43V
Therefore, output voltage will be 11.43 V.
