Discover three main measures of AC voltage.

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.

The voltage in AC circuits oscillates at a rate known as the frequency. With an oscilloscope, see and measure the length of time between signals, and calculate the frequency of an AC signal.

A general summary of electrical resistance including a comparison of AC and DC current.

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