Fundamental electrical engineering concepts and theory
Capacitors have numerous applications in electrical and electronic applications. This note examines the use of capacitors to store electrical energy....
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...
Many questions sent in to the site are in connection with motor starting and in particular star-delta. For all but the simplest application, there is...
GE have put together a time-lapse video shown flight take-off and landings at some airports. An interesting view:
The fundamental component of any analogue computer is the operational amplifier, or op amp. An operational amplifier (often called an op-amp,) is a high...
Traditionally generation of electricity has involved rotating machines to produce alternating sinusoidal voltage and current (a.c. systems). With the development...
Lamps are the essential part of any luminaire. These are the light generating components. Since the advent of electrical lighting in the middle of the...
At the beginning of the year China put the world's first 1,000 kV UHV transmission system into operation. Transmitting power at over a million volts is...
Gauss's Electrical law defines the relation between charge ("Positive" & "Negative") and electric field. The law was initially formulated by Carl Friedrich...
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...
