NOT many years ago a certain type of journalist used to compare and contrast the theorist and the practical man, to the demolition of the former and the apotheosis of the latter. Fortunately, such an ...

IN English text-books on electrical engineering one finds occasionally an attempt to elucidate some property of an electric circuit by a mechanical model. A favourite analogy is a water-tank with pipe ...

A new theory could help build future superconducting alternating-current fault-current limiters for electricity transmission and distribution systems. The work identifies design strategies that can ...

AC Fundamentals 241 discusses alternating current (AC) as the most common form of electrical power. AC waves can be viewed and measured on the screen of an oscilloscope. Alternating current is ...

The rules of the National Electrical Code are written for people who have a pre-existing knowledge of electricity. In order to make sense of the Code, you must first understand basic electrical ...

This course covers AC circuits under sinusoidal steady-state conditions using the concept of the frequency domain. Introduces the use of complex numbers, phasors, impedance and admittance for the ...

Current transfers energy around circuits. Circuit components have various properties that can be measured and then used to make circuits for control and also circuits for testing other components.
