What kind of battery can power a 40 watt light bulb?

A D or a M battery can power a 60 watt light bulb. A D or a M battery can power a 60 watt light bulb.

battery ---> light bulb chemical energy ---> electromagnetic energy (heat and light)

Usually a higher voltage will make a light bulb shine brighter; but if the voltage is too high, this can also destroy the light bulb.

Well, you could turn it off... Any light bulb which is emitting light is consuming power of some kind. There's no such thing as a "zero watt bulb".

A 40-watt bulb requires 40 watts of power. It can come from any kind of electric generator.

The kind of gas that is in a light bulb is called Argon.

Mechanic energy is converted in to light bulb , in bulb the electric energy converted into heat and light

Um, a 5 volt light bulb?

A light bulb uses electrical energy, and produces light, as well as heat.

It depends on several things. 1.) The battery level on the flash light. 2.) The reflective casing surrounding the light.

No. A light bulb is a bulb that contains a filament that gets hot when electric current is passed through it.

It is the Incandescent light bulb. Most of the energy are lost as heat

0. A light bulb no matter what kind is a hardware problem.

Electric->Heat->Light

The amount of light produced is measured in lumens, while the electric power used is measured in watts. An old-type 100 watt incandescent bulb produces about 1200 lumens. The same amount of light can be produced by a 70-watt halogen bulb, a 20 watt CFL bulb or a 15 watt LED. The power that is not turned into light is turned into heat instead.

thermal energy of course. :}

An LED, laser, or light bulb.

A light bulb is not energy, but is a device that uses electrical energy to create electromagnetic energy in the form (in part) of visible light and heat.

It kinda depends on what kind of bulb incandescent lights use filaments and emit heat, for example

Depends which kind. If it has Electrolytes you can add a small light bulb to a controlled amount of the drink. The light bulb should light up, at least dimly.

Chemical energy to electrical energy.

A light bulb uses conduction.

On lighted vanity mirrors you want to use a vanity mirror light bulb. The bulb is very round where the light is produced and is not very long.

It takes a battery that delivers the voltage that the bulb is designed for, at a current of (10/bulb voltage) amperes for a reasonable length of time.

No there isn't any kind of snake that has a light bulb on it.
