Cathode Ray Tube

The cathode ray tube is an electronic vacuum tube used for displaying electrical data in the form of images or videos on the screen. In 1897, German Physicist Karl Ferdinand Braun invented the cathode ray tube. The cathode ray tube is also known as the Braun’s tube. It is used in electronic devices such as … Read more

What Is Electrochemistry?

Electrochemistry is the study of chemical processes that result in electron movement. Redox reactions are reactions which include changes to the oxidation states of elements. Oxidation is the process when a substance loses electrons, and reduction is the process when a substance gains electrons. The substance that is oxidized is referred to as the reducing … Read more

APPLICATION OF CLASS A AMPLIFIER

An amplifier is an electronic device that is designed for the purpose of increasing signal waveform and level of voltage, current, or power and achieving this without changing other parameters of the waveform such as frequency or wave shape. Signals that are amplified are very often not sine waves, though many time they are. The … Read more

Different types of diodes

A diode is an electronic component allows current to flow easily in one direction but blocks current in the other direction. Most diodes are made from a silicon semi-conductor material. To make silicon a more effective semi-conductor the material goes through a process called doping. This involves adding impurities (holes) to the material. By adding … Read more
