Electrical deals with very high voltage and electronics
deals with very low voltage .Electrical used for very high
application but electronics we cant used.In electrical
energy gap is very low.So electrical equipment is called as
conductor .In electronics energy gap is very high .So
electronics equipment called as semiconductor .
