Discover three main measures of AC voltage.

This site provides a brief explanation of what an AC current is.

This simulation shows a simple circuit consisting of an AC voltage source and, depending on the button selected, a resistor, a capacitor or a coil.

A short summary of resistance and how it is measured. Including information on AC and DC.

AC circuits with capacitors and inductors respond to the frequency, as well as the voltage. Find the frequency value that reduces the circuit power to half the maximum.
