Motor Control AC Voltage
Young scholars demonstrate that motors work on two different voltages. They connect a single-phase AC motor to run on different voltages.

Concord Consortium: Measuring Time and Frequency
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.
