WebElectrical resistance is measured by either of two methods: constant current or constant voltage. The constant current technique sources a known current through an unknown … WebMeasurements of AC Magnitude. So far we know that AC voltage alternates in polarity and AC current alternates in direction. We also know that AC can alternate in various ways, and by tracing the alternation over time, we can plot it as a “waveform.”. We can measure the rate of alternation by measuring the time it takes for a wave to evolve ...
