This tutorial covers transistor basics and conceptually answer a question how transistor works? Transistors are backbone of electronics. They are everywhere; in discrete form, in group of millions as integrated circuit. Lets explore them.

This article is about different types of capacitor. Any piece of electronic circuit, equipment have variety of capacitors inside it. When comes to selection of capacitor for electronics circuit design, we have many options. Let’s discuss about them.

In this post, we’ll learn about reverse current protection using diode. This is basic but significant application of diode.

This article is about different types of diodes. Depending on functionality, voltage and current ratings there are several types of diode. Let’s discuss them.

This post is about What is Diode? and Why we need Diode in Circuit. The diode controls direction of current flow in circuit. It is used for AC to DC conversion (rectification), in switching application.

A resistor whose resistance value can be adjusted as per requirement is called as Variable Resistor. The two most common used variable resistors are Rheostat and Potentiometer.

Let’s discuss How Pull-up and Pull-down resistor works in Electronic Circuit. These resistors used when a constant voltage is required at input pin of a digital device (for example, Microcontroller).

Learn how to calculate resistor value using color code. When comes to measure the value of resistor we can do that by several ways. But we'll explore color code method for through hole resistor.
