The only way a light bulb could be lit without electricity would be if it wasn't an electric bulb, or the "light" wasn't from an electric filament. I once had a miner's torch that was lit by igniting acetylene gas, but I wouldn't call it a "light bulb".

Electric light bulbs will only light with electricity. There is no other way short of breaking them open and igniting something inside of them, but then they aren't electric lights anymore.

You don't. The design of an ordinary light bulb is to operate with a voltage supply.

Does a light still you electricity if there is no bulb?

No, a light fixture does not consume electricity if there is no bulb in it. The bulb is what generates light when electricity passes through it, so without a bulb, there is no circuit to complete and no electricity is being used.


Why do you need electricity to light a light bulb?

Electricity is needed to light a light bulb because the flow of electrons through the filament inside the bulb generates heat and light energy. This energy causes the filament to emit light, thus illuminating the bulb. Without electricity, there is no source of energy to power the light bulb.


Can a bulb light if electricity doesn't get to the bulb?

No, a light bulb will not light up if electricity does not reach it. Electricity is required to flow through the filament in the bulb to generate light. If there is no electrical current, the bulb will not illuminate.


Which was invented first the light bulb or electricity?

electricity because a light bulb needs electricity


What is the source of energy in a light bulb?

Electricity is the source of energy in a light bulb.


What provides the energy to light a light bulb?

Electricity provides the energy to light a light bulb. When the electricity flows through the filament in the bulb, it generates heat and light.


Where does the electricity go in a light bulb?

Electricity flows through the filament of a light bulb, heating it up and causing it to emit light. The electricity powers the light bulb, allowing it to produce illumination.


Why a light bulb stops glowing when a wire inside the bulb breaks?

When the wire inside a light bulb breaks, it interrupts the flow of electricity, causing the circuit to become incomplete. Without a continuous flow of electricity, the bulb cannot produce light. The broken wire prevents the filament from heating up and emitting light.


How do you make a light bulb in alchemy?

Electricity + Glass = Light bulb


What electricity will let battery and light bulb flow?

Direct current (DC) electricity is the type of electricity that will flow from a battery to power a light bulb since batteries provide DC power. Alternating current (AC) electricity, found in most wall outlets, typically can't directly power a light bulb from a battery without a converter or inverter.


What is the input or output of the light bulb?

Input to light bulb is Electricity and output is light.


What is the path taken by electricity through a light bulb?

Electricity flows from the power source through the wires connected to the light bulb's terminals. The electricity then passes through the filament inside the light bulb, which heats up and produces light. Finally, the electricity exits the light bulb and returns to the power source through the wiring.
