The voltage–time graph for an alternator. A – The coil is at 0°. The coil is moving parallel to the direction of the magnetic field, so no potential difference is induced.

On a voltage-time graph, this would appear as a curve alternating between positive and negative voltages - the positive and negative values indicate the direction of current close current Moving ...

This video is part of the Test & Measurement Series: XYZs of Oscilloscopes Video Series There are at least two different ways to measure voltage and time on an oscilloscope. First we’ll cover ...
