When an alternator produces AC voltage, the voltage switches polarity over time, but does so in a very particular manner.…
So far we know that AC voltage alternates in polarity and AC current alternates in direction. We also know that…
Most students of electricity begin their study with what is known as direct current (DC), which is electricity flowing in a constant…
Simple circuits involving nothing more than an AC power source and resistance, the same laws and rules of DC apply…
One of the more fascinating applications of electricity is in the generation of invisible ripples of energy called radio waves.
