The existence of electronics industry would have been impossible without Diode. It is the simplest semiconductor device which finds its applications all over in the world of electronics. This article will discuss about what is Diode, its brief history, ...
Thyristor – Working, VI Characteristics, Types, Applications, Advantage & Disadvantage
A Thyristor is basically an on-off switch to control the output power of an electrical circuit by switching on and off the load circuit in intervals of time. In this post, we will try to understand what is it, How ...
Cathode Ray Tube (CRT)
Every one must have seen TV/Computer picture tubes. Have you ever thought, How the display on TV screen comes?? Its all because of the CRT ( of any mode) used in them. CRT denotes for Cathode Ray Tube. ...
Theory behind Impressed current cathodic protection
Impressed current cathodic protection is a method for ship’s hull protection. But, before discussing the Impressed current cathodic protection, its important to know the theory and history of cathodic protection. Cathodic Protection is a method ...
Hull protection methods
Paints alone cannot accord complete protection to underwater hull. Areas above keel blocks are not always possible to protect by painting. Stern areas suffer erosion due to high turbulence caused by propeller. In these areas, chances ...
Importance of Hull protection
If we go back in history, we can understand that the man has involved himself with works and resources of sea from a long time. He has been continuously improving and producing structures for using it ...
Galvanic Corrosion
Galvanic corrosion may occur in fresh or salt water. It generally happens whenever two/or more metallic elements having unlike galvanic-voltages connects to each other electrically in the presence of an electrolyte. In other words, it ...
Corrosion
It is generally understood that Corrosion means rust and is treated like an almost universal object of hatred. This word ‘Rust’ has been specifically reserved for iron corrosion. However, Not so many ...
