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.
If the voltage of the energy from the power source is not accurate or if the neutral and "hot" (or negative and positive for direct current) wires from the energy source are not both properly connected.
Because the circuit is incomplete
The battery us not connected
If you will connect it right, it will work.
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.
A parallel circuit will not effect the other bulb. If the bulbs are in a series circuit the other bulb will not turn on.
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.
The whole circuit fails - because the action of the bulb blowing cuts the circuit.
in a series circuit or it will not work. Put it after the bulb
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.
If you will connect it right, it will work.
In that case, the entire circuit won't work.
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.
The bulb is the load of the circuit, without it you have a short circuit.
Tail light doesn't. Work with new bulb in
It should work okay.
A light bulb can be part of a circuit.
A parallel circuit will not effect the other bulb. If the bulbs are in a series circuit the other bulb will not turn on.
Electric energy powers appliances such as a radio or light bulb. It travels in a CLOSE CIRCUIT.
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.
