What useful energy is in a light bulb?

The useful energy in a light bulb is the light that it emits. When electricity flows through the filament of a light bulb, it produces light energy that we can see and use for illumination.

What are the types of energy produced by a burning light bulb?

A burning light bulb produces mainly light energy as well as heat energy. When electricity passes through the bulb's filament, it heats up and emits visible light as well as infrared radiation, which we perceive as heat.

If 100 J goes into a light bulb how much energy comes out of the light bulb in total?

The amount of energy that comes out of a light bulb is typically less than the energy that goes in, due to energy losses in the form of heat and light. The efficiency of a light bulb is determined by its design and technology. The amount of useful energy output can vary depending on the type of light bulb used.

What form of energy that is not useful when a flashlight is on?

Nuclear energy is not useful in powering a flashlight because it is not readily convertible into electrical energy that can power the light bulb in a flashlight.

What type of energy is when you plug in a light bulb?

Electrical energy is used when you plug in a light bulb. The electrical energy is converted into light and heat energy by the light bulb.
