How much electricity does electric bulb uses?
The quantity of power consumed by a light bulb is dependant on the wattage of the bulb.
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.
How much wind power to light a bulb?
You need a wind power generator to make the electric energy to hook your light to. Maybe charging a battery with the wind generator and running the light bulb off the battery will provide better service.
How much does it cost you to burn a 0 watt light bulb for 24 hours a cost of 0.085156 per kwh?
A 0 Watt bulb does not consume electric power so the cost is zero.
Why does energy saver give more light than electric bulb of same watt?
Both bulbs output the same amount of energy. The difference is in how much of that energy is output as heat vs the energy output as light. In a standard incandescent light bulb about 10% of the energy is output as light while the other 90% is output as heat. This makes the bulb only 10% efficient. For a florescent bulb the output of light is about 50% and the other 50% is output in heat. This means that a fluorescent bulb outputs five times as much light for the same wattage as a standard incandescent bulb, hence you can get the equivalent of 100 watts of light output for only 20 watts of electricity.
Is electricity the same as electric light?
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.
Why it is impractical to connect an electric light bulb and an electric heater in series?
It would not work because when two things are in series the same current has to pass through both. Normally an electric light takes much less current than an electric heater and therefore the light has more resistance. Most of the voltage would appear across the light bulb, so you would have a slightly dimmed bulb and a heater giving out very little heat. It would work if both devices were identical. Electricity supplies use a constant voltage, e.g. 120 v or 240 v, and all applicances are connected in parallel across the supply.
Why does a bulb blow?
Because to much electricity is getting through to the light bulb.
How does an electric bulb?
it works with a circuit.these tiny microscopic molecules travel through the wire. the filament, a very thin metal lets the molecules travel through, but at a much slower pace. this then causes it to burn and light the bulb up.
What is the main reason fore a light bulb to stop working?
the main reason for a light bulb to break is, the light bulb heats the tungstin wire. When the tungstin wire gets heated to much it breaks, causing thi light bulb to stop working.
How much time would a 60w light bulb to run out of light?
The average lifetime of an incandescent bulb is around 2000 hours.
What happens when you put an electric motor with higher resistance and a light bulb with less resistance in a series circuit. does the bulb light up and motor spin. or only the motor spin?
(Another possibility is: Bulb lights up and motor does not spin.)The result all depends on the relative resistance of the bulb and the motor, becausethat determines how much of the supply voltage appears across the light bulb, andhow much across the motor.That's one of the big problems with a series circuit: The performance of one devicedepends on the characteristics of the other devices in the same circuit. If you turnthe light off, the motor can't run at all. If the load on the motor changes, then thelight bulb flickers. And if you change the light bulb and put in one with a differentresistance, then the strength of the motor changes.
