if u want to pass the current u need one closed loop.
i.e. 1)Supply
2)Any resistance to the current i.e. bulb or fan
anything
3)Return path to the current.
why bcz, after passing through bulb or fan the remaining
current has to go some where. that remaining current again
we r transferring into the ground i.e. neutral. This
neutral wire will be connected to main. from main again it
will be grounded.
