## Calculation – Pull Up/Pull Down Resistors

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 …

## How to calculate AH of a battery using multimeter ?

AH calculation using multimeter First of all in order to calculate AH of a battery, we must know about it. AH – it is Amp-hour, one the battery energy capacity units. Which is equal to the multiplication of the continuous current (in ampere) supplied to battery while charging (at the time of charging it) / …

## Internet of Things(IoT), Available Technologies for IoT

What is an Internet of things (IoT) ? The Internet of things (IoT) may be a tiny device embedded in objects, machines. And things are connected to wireless networks which sends and receives information. Sometimes named as a “radio chip“, “rf module” or “IoT chip,” the IoT module contains an equivalent technology. Information circuits found …

## IoT – Internet of Things

Introduction – IoT or Internet of Things What is IoT ? The Internet of Things, or IoT refers to the devices which is connected to the internet and sharing its data on internet or to other billions of devices around the world. Due to the arrival of super-cheap computer chips and therefore the ubiquity of …

## Basics of Operational Amplifiers

Introduction – Operational Amplifier Operational-amplifiers is basically amplifier. And the basic job of an amplifier is to amplify the input signal. Why operational amplifiers ? As the name itself suggests operational, operational amplifier performs different mathematical operations. For example addition, subtraction, integration, and differentiation. So, just by connecting few resistors and capacitors, it is possible …
