Question

We know that the formula relating instantaneous voltage and current in an inductor is this: Knowing this, we can determine that if the inductor current is a sine wave, then the inductor voltage will be a cosine wave, as show in in the diagram below: How much phase shift (in degrees) is there between the voltage and current waveforms? Which waveform is leading and which waveform is lagging? Phase shift is 90 Degree, with the inductor voltage leading the inductor current (by 90 Degree) Phase shift is 90 Degree, with the inductor voltage lagging the inductor current (by 90 Degree) Phase shift is 45 Degree, with the inductor voltage leading the inductor current (by 45 Degree) Phase shift is 45 Degree, with the inductor voltage lagging the inductor current (by 45 Degree) Phase shirt is 0 Degree, with the inductor voltage in phase with the inductor current.

Explanation / Answer

phase shift is90 degrees since sine and cosine waves are perpendicular to each other &

voltage waveform leads current waveform by 90 degrees.

hence,option(a)
