Objects that produce heat and light?
Light bulbs convert energy to light. This conversion is inefficient, meaning that not all of the energy will convert to light because of the design of the bulb and the laws of physics. The energy that does not become light is released as heat, and that's why a light bulb gets hot.
Why can't you see a light bulb when it is switched on?
You can see a light bulb when it is on but it is so bright, the coil causes energy which is transferred as light.
What is an example of a common technology that does not efficiently convert energy?
Incandescent light bulbs are inefficient at converting energy into light. They are so inefficient that in many places there is no a ban on the sale or manufacture of incandescent light bulbs in favor of higher efficiency CFLs, LEDs, or halogen lights.
What is light bulb filament?
It is the extremely thin wire inside the bulb. It is so thin that when the electricity goes through produce light, when that filament breaks the bulb is not good.
When did Thomas Edison improve the light bulb?
thomas Edison didn't exactly "improve" the light bulb; he created a new type called an electric light bulb... ok so maybe he did improve it...
Why is an incadescent bulb a very inefficient light source?
An incandescent light bulb is very inefficient light source because of the amount of heat energy wasted when it is energized.
Why are heat engines inefficient?
Because much like the light bulb and fans, there's always a bi-product during the main process. So long as the heat engine makes a sound, it'll be inefficient.
What causes the bulb to light in closed circuit?
Energy flowing through the filament. In a traditional incandescent bulb most of the energy is radiated as heat which is why they are viewed as inefficient.

Why Charles Francis Brush built the light bulb?
in that time they were no light so he build the light bulb
Why does the incandescent light bulb hot?
That type of bulb makes its light by making a small piece of tungsten wire glow at around 3000 degrees Celsius. Obviously that process also produces a lot of heat so incandescent bulbs are inefficient, i.e. they produce not much light for a lot of electric power used. Tungsten is used because it has the highest melting-point of all metals.
Why do people use the light bulb?
so we can see and have light
Why can't you see a light bulb when it is switched on?
You can see a light bulb when it is on but it is so bright, the coil causes energy which is transferred as light.
What does the filament in a light bulb do to the electricity?
The filament in a light bulb forms resistance so that heat can happen. The electricity then converts to light energy and heat energy so that the light will shine.
How lighting occur?
For example, in an old-fashioned (inefficient) incandescent light bulb, the electricity passes through a thin wire, heats it up, and this heat produces light. Newer light bulbs use a different mechanism for lighting.
How do you transform electrical energy to light energy?
You use a light bulb.Such light bulbs use different types of technology; for example, the old-fashioned (and quite inefficient) incandescent bulb heats a wire, which acts as an electrical resistance, to the point where it glows.
