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 light bulb a soure of light?
Yes, a light bulb is a source of light. When current is going through the filament the resistance generates enough heat that the filament glows, producing light.
Will the bulb light if the filament is broken Why?
No, the bulb will not light if the filament is broken because the filament is the part of the bulb that creates light when electricity passes through it. Without a functioning filament, there is no source of light in the bulb.
What causes Electric shock injuries?
Electric shock injuries are caused by lightning or electric current from a mechanical source passing through the body
What is The complete path of an electric current described as?
The complete path of an electric current is described as a closed loop circuit. This means that the current flows from the power source through a continuous path of conductive materials, such as wires and components, and back to the power source. Without a closed loop, the current cannot flow continuously and the circuit will not work.
What is the filament in lights?
Filament is a thin part of incandescent bulb which is the source of electric light that electric current passes through and heated it until it produce light.
What source of light is shown in the diagram?
The diagram shows an incandescent light bulb as the source of light. It consists of a tungsten filament that emits light when an electric current passes through it, causing it to heat up and glow.
Steps of the making of the electric light bulb?
Develop a filament material that emits light when an electric current passes through it. Seal the filament inside a glass bulb filled with an inert gas to prevent it from burning out. Connect the filament to an electrical power source with a properly designed socket. Test the bulb for efficiency, longevity, and safety before mass production and distribution.
Is a filament a source of energy?
It is when it is heated by electric power, when it gives off heat and light.
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.
Why does the light bulb not work when the filament is broken?
When the filament in a light bulb is broken, it creates an open circuit, which interrupts the flow of electricity. Without a complete circuit, the electricity cannot pass through the filament to produce light. As a result, the light bulb does not illuminate.
What is the function of a source in the electric current?
POINTS
A temporary source of electric current?
A battery.
What particles create the electric current in a fruit battery?
An electric current is movement of electrons, no matter the source or cause.
One source of constant electric current is a?
Alah
What is a temporary source of an electric current called?
A temporary source of an electric current is called a battery. It converts chemical energy into electrical energy to power devices or circuits.
What do you understand by electric current?
electric current is the flow of electrons due to external energy (emf) supplied by the voltage source.
