## Resistor Calculator

Introduction This resistor calculator calculates the resistance value of different resistors connected in series or in parallel. Two simple ways to connect circuit elements as below: Resistor in Series The resistors are said to be in series when they are chained together in a single line. If you can move your finger along the wires …

## How to use pull up/pull down resistors ?

Till now you might have understood about the pull up/pull down resistors and why we need them in our digital circuits. First one we took is pull up resistors. Here you can see in image a) (i) that two resistors are connected at the input of logic device in series with 5Volt Vcc. And by …

## Pull Up/Pull Down Resistors

In all digital circuit boards we surely find Pull up/Pull down resistors in it. Here we are going to learn what it does, how we can use it in our circuit and calculations for finding values of these resistors. What are Pull UP/ Pull Down resistors ? As the name suggests pull up / pull …

## Calculation for Voltage Divider

In previous post we had gone through the formula and the circuit used as voltage divider using two resistors. Example Circuit : A resistive divider is the case where both the resistors R1 and R2, are purely resistive (Image 1). Substituting R1 and R2 into the previous expression gives: Given : Vin = 9V , Vout = 3V …

## Resistor as a voltage divider

Let us learn here how to use resistor as voltage divider. It is a passive linear circuit which gives fraction of voltage of the input side. How ? We can simply say that voltage divider divides the input voltage (Vin) in a specific network of two resistors connected in series. These two resistors are connected …

## Use of components practically

Practically … ! you might be thinking well all the components in a product is used practically. Yes you are right, saying practically means we will learn about component example circuit so that we can also apply it practically. It will be cool . Merely studying books you will not be able to know the …
