why the earth pin is thicker than other pins in a plug? If
it is for reducing resistance, then why the copper earth
wire is not so thick as earth pin of socket?
Answer Posted / avnish
you are absolutely correct that it is for redusing the
resistance so that current can pass,As we all know that
current follows min. resistance path. As far your next
question if we keep earth wire thick as pin of socket than
it will be very costly comparision to previous one .So as
this will considered as cost point of view....thanx
