Description should include

- defining
  - alternating current
  - cycle
  - alternation degrees
  - frequency
  - sine
  - cosine
  - tangent
  - hertz
  - peak
  - sine curve
  - amplitude
- measuring AC voltage, using a meter and an oscilloscope
- measuring the frequency and amplitude of an AC signal, using an oscilloscope and a signal generator
- calculating instantaneous and average values and effective (root mean square [RMS]) voltage or current
- performing RMS-to-peak, peak-to-peak, frequency-to-time, and time-to-frequency conversions
- measuring current and voltage in an AC resistive circuit.

Process/Skill Questions:

- What does phase refer to in sinusoidal waveform?
- What are some symmetrical waveforms that are not sinusoidal?
- What are circumstances where AC is used instead of DC?
