Current begins to flow through the tungsten filament of the wire. Because of its high resistance, the wire heats up till the point that it starts glowing, producing light from the bulb.

What circuit do you need for two switches one bulb?
wiring diagram of one bulb in two switches.. example, if switch a- on then switch b- off the bulb is on, switch a- off then switch b- on the bulb is on, switch a- on then switch b- on the bulb is off, switch a- off then switch b- off the bulb is off..
When the switch is closed which light bulb will light light bulb 1 2 or 3?
It depend on where the switch is located in the circuit.
What if your switch is on but the bulb is off?
There could be a series of problems. First, are all the wires hooked up? Is the bulb burned out? Is it just the switch that is not working? You should go and put in a new bulb, and see if it was just burned out.
Why does light appears when you flick the switch?
Operating the switch completes the circuit between the power source and the bulb.
What happens when a battery light the light bulb?
When the switch is turned it completes an electrical circuit. The circuit amperage flows through a high resistance filament in the bulb and it starts to glow. The bright glow from the filament and the reflector behind the bulb is what creates the flashlights beam.
What happens when you switch on an incandescent bulb?
The surrounding area adjacent to the light bulb becomes easier to see.
What happens when a bulb ammeter battery and switch are put connected together?
the bulb will glow and ammeter will show the reading
If you unscrewed the second bulb in the series circuit when it was on explain what happens to the first?
Unscrewing any bulb in a series circuit turns them all off. This is the same as opening the switch that controls them.
What circuit do you need for two switches one bulb?
wiring diagram of one bulb in two switches.. example, if switch a- on then switch b- off the bulb is on, switch a- off then switch b- on the bulb is on, switch a- on then switch b- on the bulb is off, switch a- off then switch b- off the bulb is off..
What is the switch and the bulb in electricity?
A switch is used of stop the current flow in a circuit and the bulb can be classed as the load in a circuit.
How do you replace bulb on fan switch Toyota avensis?
How to change bulb behind switch of fan Toyota Avenses
What is the difference if a switch is before or after a bulb in a circuit?
It is a safety concern. With the switch before the bulb, the bulb is completely isolated from the potential source when the switch is turned off. With the switch behind the bulb, even if the switch is turned off, the potential source is still at the bulb. If any of these lamp holder parts touch the ground when removing the bulb the circuit will short out and trip the breaker. If you are grounded and touch any of the lamp holder parts you will get a nasty shock.
When the switch is closed which light bulb will light light bulb 1 2 or 3?
It depend on where the switch is located in the 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.
Why doesn't a bulb light up until you press the switch?
A switch completes the circuit, allowing electricity to pass from the cell (battery) to the bulb.
When you open the switch what happen to the bulb?
It go out.
What would not be needed in the conducting loop in order to light a bulb - a positive terminal of battery - a switch - a negative terminal of battery - or a bulb?
The switch is not needed.
