How to calculate value of resistors ? It is obvious that every electronics device consume some current to operate and have some input impedance. And therefore voltage drop occurs across these resistors. These resistors should not be too low or high value otherwise it will result in misbehaving of the circuit you want to operate …
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 …
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 …
