At t = t0, the current through a certain inductance is zero. A voltage pulse is applied to the inductance between t0 and t0 + ?t, and the current through the inductance increases to If . What can you say about the peak amplitude Vm and area under the pulse waveform (i.e., voltage versus time)? What are the units of the area under the pulse? What must happen to the peak amplitude and area under the pulse as ?t approaches zero, assuming that If remains the same?
