Why is there zero current when a light bulb burns out?

6. Why is there zero current when a lightbulb burns out? When the filament can no longer handle the heat from the energy of the current passing through it, it will melt and break. When the filament breaks, there is no conductor for the electrons to pass through to continue the circuit, resulting in zero current.
