When selecting a cable, the performance of the cable under fault conditions is an important consideration. It is important that calculations be carried...

Gauss's Electrical law defines the relation between charge ("Positive" & "Negative") and electric field.  The law was initially formulated by Carl Friedrich...

In electrical engineering, Network Theory is the study of how to solve circuit problems. By analyzing circuits, the engineer looks to determine the various...

Most installations involve some form of lightning protection system which is connected to an earth electrode.  The function of the earth electrode is to...

If you want to check a circuit is dead (not live), you should always use the three point method. First check a known live circuit, then check the dead...

If you have a great idea or invent something the last thing you want is someone to steal the idea. One of the things you can do is protect the intellectual...

Laplace transforms and their inverse are a mathematical technique which allows us to solve differential equations, by primarily using algebraic methods...

The calculation of current in a three phase system has been brought up on our site feedback and is a discussion I seem to get involved in every now and...

IEC 60287 "Calculation of the continuous current rating of cables (100% load factor)" is the International Standard which defines the procedures and equations...

Motor starting and its associated problems are well-known to many people who have worked on large industrial processes. However, these things are, of course...
