A light fitting which is supplied by 110v is therefore connected to a hot wire and neutral. Can someone explain to me what happens when the sine wave goes negative? Does voltage/current travel thru the neutral wire? From what I'm led to believe about a light fitting, the current goes one way then the other very quickly across the filament.

man,welcome to electricity 101.anytime you have electricity flowing,and, if you're in the good ol USA,then you have what is known as 60 cycle power.which means power is going back and forth (or is it forth and back, i forget) 60 times a second.and yup, it uses the neutral wire all the time. you see,power has to get there,then it has to come back on something. kinda like opening your faucet,the water came in,then it left down the drain.
