Answer Posted / umair qayyum
Deviation of an ac signal from pure sinoside causes the
harmonics to exist.They are generated both because of non
linear loads; and generators because of the nonuniform
srator windings and magnetic fields in practical case.
When a sonosidal voltage is applied to a linear load,a
proportional current is also drawn with it.But when it is
applied to a non linear load,it causes the current to vary
disproportionately with the voltage due to which
nonsinosidal waveforms are created containg
distortions,whereby 50/60 hertz frequency contains numerous
waveforms superimposed upon it which are the multiple
frequencies of the normal 50/60 hz sine wave.
