An inductor filter connected in series with a resistive load provides a
(a) smoothing of the output voltage waveform
(b) smoothing of the input voltage waveform
(c) smoothing of the output current waveform
(d) smoothing of the input current waveform
I had been asked this question by my college professor while I was bunking the class.
I want to ask this question from Filters-2 topic in chapter Diode Rectifiers of Power Electronics
