Varistor – Symbol, Working, Types and Applications The small package of resistance, the resistor is used in so many circuits, in so many forms, that it is almost…
Ballast Resistor – Working, Types, Applications & Uses According to the English dictionary, “ballast” means something that gives stability. Thus when referring to an electrical ballast, we mean…
Digital Potentiomter – Working, Internal Structure & Applications One of the most common types of variable resistors is the potentiometer. Potentiometer or “pots”, are three terminal devices, used…
Resistor, the most basic yet essential passive component of an electronic circuit, is nothing but a device that restricts the flow of current. So why is it called…
Ultimate Guide on Resistivity and Electrical Conductivity We know what the electric wires are made of; they are either made of copper or aluminum. We also know that…
A look into the electronic circuit board mostly shows wires with colorful bands, called resistors. These color bands indicate the values of those resistors like the identity card…
The good definition of Pulse Width Modulation (PWM) is in the name itself. It means modulating/varying the width of the pulse (Not the frequency). To best understand what…
In this article, we learn about PN junction diode characteristics in detail – like how to bias a PN junction (Forward & Reverse bias methods), behavior of PN…
Whenever someone decides to learn electronics, the first question that comes to his mind may be – “Where shall I begin?”. I would say, one shall begin at…
A voltage regulator is one of the most widely used electronic circuitry in any device. A regulated voltage (without fluctuations & noise levels) is very important for the…
In this article, we are going to learn a little deep about break down characteristics of PN Junction Diode and how “reverse break down” characteristics is put into…
