Fundamental electrical engineering concepts and theory
I have been thinking recently that there appears to be less professional integrity around than when I first started my career in electrical engineering...
Coils of wire on the rotor carry a d.c. current which generates a magnetic field. A stator magnetic field is created using either permanent magnets or...
Electrical notes are a collaborative collection of electrical engineering information and educational material. Any registered user can add content. ...
Traditionally generation of electricity has involved rotating machines to produce alternating sinusoidal voltage and current (a.c. systems). With the development...
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...
GE have put together a time-lapse video shown flight take-off and landings at some airports. An interesting view:
Ever wondered what kind of power an aircraft uses when parked at the airport stand. Normally the aircraft generates it own power, but when parked with...
IEC 62305 'Protection against lightning' requires a risk assessment be carried out to determine the characteristics of any lightning protection system...
Over recent years the Lithium Ion battery has become popular in applications requiring high power densities with small weight and footprint. Today Lithium...
Most installations involve some form of lightning protection system which is connected to an earth electrode. The function of the earth electrode is to...
