AC voltages cause no net movement; the electrons oscillate back and forth in response to the alternating electric field.

If an AC voltage is passed across the sheet a stylus will be able to detect the potential at any point.

These receivers output a signal composed of two AC voltages.

AC voltage may be increased or decreased with a transformer.

With a further increase in t, the AC voltage becomes negative, and the field in the avalanche region drops below its critical value.

This situation produces an additional phase shift of 90 between the AC voltage and the diode current.

The AC voltage is the line frequency of the mains.

But power plants produce AC voltages, so the electrons just move back and forth along the wire.

Modern transmission grids regularly use AC voltages up to 765,000 volts.

Unlike in earlier classes, changeover between the two AC voltages can be made by the engineer while on the move.
