Capacitors are widely used in electrical engineering for functions such as energy storage, power factor correction, voltage compensation and many others...

A fundamental concept behind the operation of alternating current systems is that voltage and current waveforms will be sinusoidal – a Sine Wave. This...

How often installations are inspected is up to the owner of the installation, provided such durations do not exceed any regulatory maximums in force. ...

Fault calculations are one of the most common types of calculation carried out during the design and analysis of electrical systems. These calculations...

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...

Power factor is the ratio between the real power (P in kW) and apparent power (S in kVA) drawn by an electrical load. The reactive power (Q in kVAr)...

The mobile phone was born in 1973. They were the size of a brick and weighed a couple of kg, making them difficult to fit into your pocket. At a few thousand...

Often us engineers get so bogged down in equations, using software, producing drawings and writing specifications that this becomes the sole focus.   ...
