A light bulb is not lit when the swtich is not connected to the wire becasue there is no flow of electricity, specifically, flow of electrons. By disconnecting the wire, the bulb is no longer connected to the electricity source.

Will the circuit with two batteries a bulb and a motor work?
If you will connect it right, it will work.
If a light bulb is missing in a series circuit will the bulb light?
If one light bulb in a series circuit fails, all the other light bulbs will go out, until the failed bulb is replaced and the series circuit is completed again.If one light bulb in a parallel circuit fails, all the other light bulbs will still work.
In which circuit did screwing out one bulb not influence the lighting of the other bulb?
A parallel circuit will not effect the other bulb. If the bulbs are in a series circuit the other bulb will not turn on.
What materials are conductors in a torch?
The conducting path of a torch is a simple circuit: Battery to switch, switch to bulb, bulb back to battery. Provided the switch is on, and there are no breaks in the circuit wiring (and the bulb is good), the torch should work.
What happens to the potential difference of a bulb that burns out in series circuit?
The whole circuit fails - because the action of the bulb blowing cuts the circuit.
Where would you put an ammeter in a circuit?
in a series circuit or it will not work. Put it after the bulb
If the filament of the bulb is broken would the circuit be complete?
If the bulb's filament is broken, the whole circuit becomes open. If the bulb is in a series circuit or is the only bulb, the electricity would no longer flow. If the bulb is in a parallel circuit, along with other bulbs, then only the blown bulb would go out, and the other bulbs would still work.
Will the circuit with two batteries a bulb and a motor work?
If you will connect it right, it will work.
What happens when a light bulb is broken in a series circuit?
In that case, the entire circuit won't work.
If a light bulb is missing in a series circuit will the bulb light?
If one light bulb in a series circuit fails, all the other light bulbs will go out, until the failed bulb is replaced and the series circuit is completed again.If one light bulb in a parallel circuit fails, all the other light bulbs will still work.
What is a bulb's job in a circuit?
The bulb is the load of the circuit, without it you have a short circuit.
How would you troubleshoot a light circuit that does not work?
Tail light doesn't. Work with new bulb in
Will a 117 volt led bulb work in a 110 volt circuit?
It should work okay.
Is circuit part of a light bulb?
A light bulb can be part of a circuit.
In which circuit did screwing out one bulb not influence the lighting of the other bulb?
A parallel circuit will not effect the other bulb. If the bulbs are in a series circuit the other bulb will not turn on.
In what type of circuit does eletricity travel when it does work?
Electric energy powers appliances such as a radio or light bulb. It travels in a CLOSE CIRCUIT.
What materials are conductors in a torch?
The conducting path of a torch is a simple circuit: Battery to switch, switch to bulb, bulb back to battery. Provided the switch is on, and there are no breaks in the circuit wiring (and the bulb is good), the torch should work.
