What causes the bulb to light in a closed circuit?
In a closed circuit, electrical current flows from the power source through the wires, through the bulb, and back to the power source. When the current reaches the filament inside the bulb, it heats up and emits light, causing the bulb to light up.
Can oranges light a light bulb?
No, oranges cannot light a light bulb because they do not produce enough electricity or energy to generate light in a light bulb. Oranges do not have the capacity to function as a power source for a light bulb.
What does a light bulb have to do with an electrical light source?
A light bulb is a source of electric light. In an incandescent light bulb, the glass bulb forms a protective shield around a glowing filament. The air inside the glass bulb is removed, or replaced with an inert gas. Electric current is passed through a thin metal filament (usually tungsten), which causes it to glow white hot, giving out light. The protective bulb stops the filament from burning up, as it has no Oxygen.
Is a CFL bulb natural source of light?
You do not found C.F.L. bulb in nature as such. So it is an artificial or man made source of light. It consumes very less energy. As it does not gives out heat.
WILL 103 VOLTS LIGHT A 60 WATT LIGHT BULB?
Yes, a 103 volt source will light a 60 watt light bulb. The relationship of the bulb's wattage output at a lower voltage, as to the normal voltage that the bulb is rated to operate on, the light output will be lower.
Why can't a bulb turn on without electricity?
An incadescent bulb lights up because the voltage source creates a current through the filament of the bulb and it heats up because of its composition and gives off light as a result. No electricity, no voltage and no current.
Why is a light bulb so inefficient?
A traditional incandescent light bulb is inefficient because it produces more heat than light, wasting energy. Only about 5-10% of the energy consumed by an incandescent bulb is converted into visible light, with the rest being wasted as heat.
What causes the bulb to light in a closed circuit?
In a closed circuit, electrical current flows from the power source through the wires, through the bulb, and back to the power source. When the current reaches the filament inside the bulb, it heats up and emits light, causing the bulb to light up.
What is the source of energy in a light bulb?
Electricity is the source of energy in a light bulb.
Is a light bulb an energy source?
No.it uses energy sources (electrical energy to light up
Is a bulb a source of energy?
No, a bulb is not a source of energy. A bulb simply converts electrical energy into light energy. The electrical energy is usually provided by a power source, such as a battery or a power outlet.
Is a light bulb a source?
No.it uses energy sources (electrical energy to light up
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.
Will the light bulb light up if you connect a wire to it?
No, a light bulb needs a closed circuit with a power source, such as a battery or electrical outlet, in order to light up. Simply connecting a wire to a light bulb without a power source will not allow it to light up.
How must the light bulb be connected in order for it to light up?
The light bulb must be connected in a closed circuit with a power source, such as a battery or electrical outlet, for it to light up. This means that the positive terminal of the power source must be connected to the positive terminal of the light bulb, and the negative terminal of the power source must be connected to the negative terminal of the light bulb. This allows the flow of electricity to power the light bulb and make it light up.
How can an electric bulb be considered as an extended source of light an as point source of light?
Either, depending on the situation. If you look at it from far away, the light seems to come from a single direction, and can be simplified as a point-source. If you are very close, the light comes from different directions, and such a simplification is no longer correct.
How many amps are needed to run a light bulb?
If you divide the watts of the bulb by the supply voltage, that is the current. For example a 60 w bulb on a 240 v supply gives a current of 60/240 which is ¼ amp.
