What does the filament of a light bulb allows the light bulb to change electrical energy to?
The filament of a light bulb overs enough resistance to current flow, that the filament heats up so much that it will glow and produce visible light.
Does the size of the light bulb affect how much energy it uses with wire and a battery?
No, only the resistance of the filament counts (normally marked as "wattage" on the bulb).
Why Led bulb are better than filament bulbs for maximum reduction in the consumption of electrical energy explain?
LEDs produce visible light and not heat. Filament bulbs use much of their energy to produce heat. The LED bulb produces more light per watt consumed.
What happen to an electric current after it passes through each bulb?
There is a piece of filament in every light bulb, which has so much friction that when the electric current passes through it, heat energy is produced. This heat energy is then converted to light energy.
Is a light bulb an example of light energy or of electrical energy?
A light bulb converts energy from one form to another: from electrical energy to thermal energy in the form of light and heat. Most light bulbs which have an incandescent filament convert electricity into some light energy plus a lot more heat energy, whilst the type of light bulbs which use fluorescent tubes create much less heat and thus require much less electrical energy to run. Typically, to produce the same amount of light energy, compact fluorescent light bulbs require only 20% of the electrical power drawn by incandescents.
How does the incandescent light bulb work?
Current passes through the filament of the bulb causing it to heat up. When it heats up, it becomes so hot it incandesces. That means it radiates light. When the filament is white hot, it radiates light across much of the visible spectrum. Incandescent lights also waste a lot of energy which comes out as heat.
Why do lightbulbs get so hot?
The main component of an incandescent light bulb is the metal filament (the spiral). The filament is heated up by the AC current, when the lamp is turned on. The heat excites the metal ions so much that they radiate energy in the form of light. The spectrum of the radiation spans from visible (the warm light you can see) to invisible (infrared, which is heat). Heat is really infrared emission, which is still 'light' in physics terms.
Why are filaments of bulb coiled?
They have to be coiled in order for them to be long enough to produce enough heat, which produces the light in a small space. Otherwise the light bulb would have to be much larger.A filament bulb is coiled to allow a much longer filament to fit into a tiny space. It also reduces the amount of gas which flows across the inner portion of the filament.
What would happen to the filament in an IR lamp if too much current flowed into it?
The answer is no. However, it will run out of electricity if you put a lot of energy into the light bulb when you switch it on. Thank you for asking young fellow person who is unknown to me. -Your fellow friend
What will happen if a light bulb gets too much electricity?
If its an incandescent bulb the filament burns out; depending on the voltage put through the bulb (and the operating voltage of the bulb) the results can be quite spectacular. Normally the filament will burn out with a bright flash, if the voltage is high enough the bulb may explode.
Different color light bulb affect how much energy it has?
No, Colored light bulbs holds the same amount of energy a regular light bulb holds.
Is light the same as electricity?
Electricity is not the same as electric light. Electricity is the flow of electrons from one atom to the next. As electrons travel through the filament of a light bulb the resistance of the filament opposes the flow of current, which creates heat. The filament will heat up so much that it produces a visible light.
