Alternating Current Terminology
Please contribute to the Glossary. I don't care how silly you definition is. This is just a bit of fun.

Opposition to current flow caused by a capacitor when an AC supply is used.
Strangely enough the higher the frequency the lower the capacitive reactance.
A device that throws electrons at the middle of a screen, while magnets make the deviate from their intended destination.
The frequency that is supposed to be on the cable.
You know. The one without all the other shit.
Any frequency that is a multiple or submultiple of the supply frequency.
First harmonic is the same as the fundamental frequency.
Second is twice the fundamental frequency
Third is three times bla bla bla, you get the picture.
Circuit Impedance is a combination of Resistance and Reactance in an AC circuit.
All circuits both AC and DC (exc superconductive) contain Resistance (ohms). Only AC circuits contain reactance(ohms).
Therefore when dealing with AC circuits to find the full opposition to power we must know the reactance(X) and the resistance(R), the correct mathematical combination gives us the circuit impedance(Z).
Opposition to current flow caused by a coil when an AC supply is used.
INSTANTANEOUS value of an alternating voltage
The INSTANTANEOUS value of an alternating voltage or current is the value of voltage or current at one particular instant.
non-SI unit of energy, used by electricity authorities for billing, equal to 3.6 megajoules. The symbol is kW.h, which is sometimes sloppily written as kWh.
