What is the resistor inside a light bulb?
In an 'old fashioned' incandescent light bulb, the only electrical part inside is the filament wire itself. When you put a meter across a cold bulb and measure the resistance, you're measuring the resistance of the filament. More modern and more efficient artificial light sources, like fluorescent tubes, LED lights and CFLs, have additional electronic components inside the structure of the bulb.

How does Thomas Alva Edison's light bulb work?
Michael Faraday's made a light bulb with a platinum wire, he put it in a small glass globe, and attached it to a low voltage source. it glowed and produced light. Platinum is expensive. It only worked at low voltage. Others made lightbulbs. Edison decided a light bulb was a good idea but it needed to be made inexpensively. It needed to work at a higher voltage. The source of the electricity needed to be different from the place where the light bulb would be used. He looked for a material that could be made inexpensively and could last. It needed to be able to take higher voltage. He heated some thread until it turned to carbon. Then he made a vacuum inside a light bulb. He put the thread inside the bulb. It worked. He created a light bulb. It could be made inexpensively. It could work at a fairly high voltage.
How does a battery make a light bulb work?
If you place an end of a wire on the negative or positive side, put the outer metal part of the light bulb's cap on the other, and place the other end of the wire on the light bulb's cap's inner metal part, it will turn on.TipBefore you try to do this, always check that the voltage of the battery is equal to, or a bit less than, the voltage of the light bulb!Otherwise the light bulb may only give out a very bright flash and could easily be destroyed.
What happens when you put an electric motor with higher resistance and a light bulb with less resistance in a series circuit. does the bulb light up and motor spin. or only the motor spin?
(Another possibility is: Bulb lights up and motor does not spin.)The result all depends on the relative resistance of the bulb and the motor, becausethat determines how much of the supply voltage appears across the light bulb, andhow much across the motor.That's one of the big problems with a series circuit: The performance of one devicedepends on the characteristics of the other devices in the same circuit. If you turnthe light off, the motor can't run at all. If the load on the motor changes, then thelight bulb flickers. And if you change the light bulb and put in one with a differentresistance, then the strength of the motor changes.
How do you change the light bulb in an oven?
To change the light bulb in an oven, first make sure the oven is turned off and cool. Locate the light bulb cover inside the oven and remove it. Unscrew the old light bulb and replace it with a new one of the same type. Screw the new bulb in place and put the cover back on. Turn the oven back on to test the new light bulb.

How can I replace the light bulb in my fridge?
To replace the light bulb in your fridge, first unplug the fridge for safety. Locate the light bulb cover inside the fridge and remove it. Unscrew the old bulb and replace it with a new one of the same type. Screw the new bulb in place, put the cover back on, and plug the fridge back in.
How can I replace the light bulb in my refrigerator?
To replace the light bulb in your refrigerator, first unplug the refrigerator. Locate the light bulb cover inside the fridge and remove it. Unscrew the old bulb and replace it with a new one of the same type. Screw the new bulb in place, then put the cover back on. Plug the refrigerator back in and the new bulb should be working.
How do I replace the light bulb in my freezer?
To replace the light bulb in your freezer, first unplug the appliance for safety. Locate the light bulb cover inside the freezer and remove it by twisting or pulling it off. Unscrew the old light bulb and replace it with a new one of the same wattage and size. Finally, put the cover back on and plug the freezer back in.

Does a light bulb affect water?
Not really, but the light bulb might not work if it's on and you put it in water.
How do you change the rear light bulb on 2002 Volkswagen beetle?
Open the hatch. Right behind the light fixture that contains the bad bulb is a cover plate inside the trunk. Remove it and reach inside. You'll find two big plastic nuts that hold the fixture in place. Remove both (they turn with the hand) and push the fixture out of the fender. Unhook the wire to the bulb, twist the socket to get it out, change the bulb, put the socket back in and reconnect the wire, put the fixture back in, put the nuts back on and replace the cover.
How many orange does it take to light a light bulb?
None! as Oranges can't either put up nor light an light bulb! ;)
Is an light bulb charge of electricity?
Well if you brought a light bulb friom a shop then no but when you put the light bulb in the the thing on where it goes then yes it does because the light is on the you are going down on your power
Can a bulb light up if no electricity is running through to it?
Simply put, no. A light bulb lights up because the filament inside (the thin wire that often breaks) has a lot of resistance in it, then when electricity flows through it, it heats up and glows brightly.
