Why do we use only Sinusoidal Wave in AC supply why not the
Square,Triangle or Sawtooth etc?
Answer Posted / r k sinha
there r mainly two reason for using sine wave in ac supply:
(i)it is easy to produce by rotating coil under magnetic feild..and
(ii)all the function exist in world can be break down under the summation of many sine function by a method called fourier transformation..so it is easy for us to derive all result for sine wave...
