Nnnnn, That is correct. As the first electrons go into the light, they will cause charge to build up, since they have nowhere to go. Charge repels other charges of similar type, so they will prevent any more charge from entering the light, and the current will be zero, so no heat will build up to heat the filament.
Now for my next questions, is there any heichi timtza (set of circumstances) in which you could light a bulb with only one wire to the bulb? Also, are there any circuits that work despite the fact that there is an insulator breaking up the continuous metal connections.
