Hi,
If I remember correctly, if one applies an alternating voltage across an inductor then the back emf produced by the inductor increases with the frequency of the voltage. However when I decrease the frequency of the voltage to less than 100hz and I plot a trace of voltage against time across the inductor the waveform becomes seriously distorted. This isn't a problem with my signal generator and when I turn the frequency up the distortion dissapears. I'm just wondering why this happens only at low frequencies, and I would have thought the back emf would be larger at high frequencies, distorting the waveform to an even greater degree?
Cheers,
Zachary.
