## Logic Circuit Lectures – Decoupling a Must for the Logic ICs

Simply by adding a 100n decoupling capacitor as close as feasible to the supply terminals of logic ICs, a sound and foolproof functioning of the circuit can be ensured.

## Ghost Detection Equipment – Learn to Build Your Own RF Detector

Basically it is a super sensitive RF detector but one may delve into some other interesting unnatural facts and make it work as a “ghost detector.”

## DC to DC Battery Charger – Learn How to Construct a Simple Mobile Charger

Learn how easy it is to construct a mobile phone charger, which can charge your mobile phone battery right from your vehicle itself anytime, anywhere.

## How to Upgrade And Test Zener Circuits? Ways to Counter Zener Instability and Band Gap

In the influence of an increase in ambient temperature few electrons in the valence band acquire sufficient energy and escape to the conduction band. The gap between this valence band and highest energy band (conduction band) is termed as band gap. We will find ways to control this.

## What is a Tunnel Diode? Special properties of the Esaki Diode and its Uses

Though not so popular nowadays, due to its unique properties and characteristics, tunnel diodes, also called Esaki diodes, are something worth discussing. Let’s learn exactly what a tunnel diode is.

## Electronic and Pneumatic Controls Analyzed

## How to Build a Bridge Rectifier – How a Rectifier Works in Half-wave, Full-wave, and Bridge Configurations

In this article we will focus on the working of the rectifier diodes in three standard configurations of rectifier circuit, namely half wave rectifier, full wave, and bridge rectifier. Their advantages and disadvantages and how to build a bridge rectifier are also discussed here.

## How a Diode Rectifier Works – Testing and Low Forward Voltage Drop in Rectifier Diode Explained

This article explains the characteristics and use of diode rectifier circuits, as well as detailed information regarding the process of rectification. The article also deals with testing procedures in simple steps that can be very handy for new electronic enthusiasts.

## Causes and Prevention of Corrosion

A large quantity of iron and steel is damaged because of corrosion, causing huge losses that may have been minimized by the adoption of appropriate preventive measures. Corrosion products from oxidation do not adhere to the metal surface, and the resultant pitting deteriorates the structure.

## Air Conditioning and Outside Air Requirements

In this article, the requirements of outside air for air conditioning will be discussed, including the requirements of oxygen and dilution.
