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 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.
How much wind power to light a bulb?
The amount of wind power needed to light a bulb depends on the size of the bulb, its wattage, and the efficiency of the wind turbine. As a rough estimate, a 60-watt bulb could be powered by a small wind turbine with an output of around 400-1000 watts.
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.
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?
In a series circuit, the total resistance increases with the addition of components. If the electric motor has higher resistance than the light bulb, most of the voltage will drop across the motor, causing it to spin, but the light bulb may not light up or emit a dim light, as it receives less voltage due to its lower resistance.
Why does a bulb blow?
Because to much electricity is getting through to the light bulb.
Was the light bulb invented in accident or in purpose?
The invention of the light bulb was intentional. Thomas Edison and his team conducted numerous experiments over many years to develop a practical and commercially viable electric light bulb. It was the result of deliberate effort and scientific exploration, rather than a chance discovery.
What does the number on the top of a light bulb indicate?
The number on the top of a light bulb indicates the wattage of the bulb, which is a measure of the amount of power the bulb consumes. This can give you an idea of how bright the light will be and how much energy it will use.
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.
