No power is used. The lamp in the light fixture is the load of the circuit. The load resistance is what makes the current flow. When the current flows through the filament's resistance, heat and light are generated. With no lamp in the fixture, the circuit's voltage potential is still at the socket contact points and if touched could cause you a shock. This is a good reason to shut the fixture off at the switch when removing the burnt out bulb and replacing it with a new one.

∙ 10y agoyou need some form of electricity to make an incandescent bulb work. The filament is heated by electricity passing through it. Without electricity, there is no heat to make the filament glow, and therefore no light.
The only way would be to somehow heat the filament to the point it glows without using electricity.

For electricity to be used there has to be a circuit, a loop for electricity to travel in.
Without a bulb, the loop is broken and no electricity is used.

What is the alt code for light bulb?
you can make a light bulb by holding alt + 20.
HOW did the light bulb make life better?
The light bulb is safer and easier to use than gas lamps, and electricity is easier to distribute for the purpose of street/home lighting than gas. A cheaper, safer, and easier means of bringing light to the darkness was born with its invention.
How do you make electricity out of a light bulb fifth grade projects?
You would need tin foil ,3 volt battery and a bulb.First you wrap the tin foil around the battery and then attach the bulb your switch will be the opposite side where you place the bulb,if you press i will turn on and if you leave it will turn off.I hope that's helpful.
What is inside in light bulb?
That powder is Talc, it is used to coat the inside of the bulb to make the light more opaque so that it is less harsh on the eyes.
What important improvement did Edsion make to Joseph Swan's light bulb?
the dubion
How do you make a light bulb in alchemy?
Electricity + Glass = Light bulb
How do you make electricity with old foods?
you can make electricity by using food if you make an electric circuit and connecting it to an light bulb and when the light turns on you have electricity
What uses light energy to make electricity?
to give load from bulb to ballas
What is the most commonly used way to make light?
Before the light bulb was invented, people used lanterns, candles, and fire for light. Today, with all the technology going on, we use electricity to produce light such as for the light bulb. So the most commonly used way to make light is by electricity.
What three objects make a light bulb glow?
A power source (of electricity), a means to transport this power (conductors/wires), and the light bulb itself
What was the purpose of Thomas Edison's light bulb?
To make light from electricity and last a long time doing so.
How do you make a light bulb in little alchemy?
Light and glass. Light: electricity (Energy + Metal) Energy: Fire + Air Metal: Fire + Stone Stone: Air + Lava Lava: Earth + Fire Glass: Fire + Sand Sand: Stone + Air Your welcome :)
What experiments did Thomas Edison conduct with electricity?
Thomas Edison invented stuff .EX:first light bulb
Can you give me 2 fact about the incandescant light bulb?
-It's a very old technology quickly being replaced by newer more efficient technologies. -The light produced in the bulb is created by electricity heating up a filament inside the bulb creating light. This wouldn't be possible without the bulb however, since oxygen would quickly end this reaction of the filament through oxidation.
What circuits are closed paths that will allow electricity to travel in a loop and make a light bulb work?
a switch
How do you make bulb light using a switch?
In a theoretical ciucuit, a switch is not essential. What is needed is a source of electricity.
Could you live without the light bulb being invented?
yes because fire has always been use as light so definatly you can live without the invention of a light bulb and a light bulb was invented to make life much more easier
