## Ohms Law – Voltage, Current & Resistance Relation, When Not Applicable

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 ...

## Power Factor – Power Triangle, Types, PFC, Applications, Advantages

Power Factor is an important aspect in any electrical system. It indicates the quality of design and management of an electrical installation. It determines how effectively incoming supply is used in the electrical system. In this post we will discuss ...

## Operation of Impressed current cathodic protection

Earlier, We had discussed about the theory behind the use of Impressed current cathodic protection. To refer the aforesaid post, visit https://electricalfundablog.com/blog/?p=731 . Lets discuss how the operation ...

## 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 ...

## Degaussing coils

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 ...
