The instantaneous emf is expressed as:
The instantaneous value of the emf is the projection of the phasor on the horizontal axis.
The figure shows emf phasors a, b, and c.
For each, what is the instantaneous value of the emf?
At this instant, is the magnitude of emf represented by phasor a increasing, decreasing, or holding constant?
