Electrical Resistance is termed as the physical property of a substance that opposes the flow of current. This post will discuss in detail about what is Electrical Resistance, How to Measure it, Resistance as a function of Temperature and types of Resistors. What is Electrical Resistance Electrical Resistance is defined as the ...

Ohms Law is definitely one of the most important mathematical relationship between Voltage, Current and Resistance. Ohm's Law defines the relation between the voltage across a load (resistance) and the current flowing though it. This post will discuss what is Ohms Law, Understanding it through a simple circuit, units of ...

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 of controlling corrosion and is based on electrochemical process. In ...

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 of galvanic corrosion are more due to presence of bronze ...

The potency of a magnetic field is measured in terms of Gauss. And therefore, by definition, degausse means to reduce/eliminate the strength of the magnetic field. Degaussing coils are used to reduce the effect of Earth magnetic field on the ship’s magnetic field.
