Lamp Structure

What is the main component of an incandescent lamp?

• Silver rod

• Aluminum wire

• Tungsten filament

• Copper coil

Describe the structure of an incandescent lamp.

• The structure of an incandescent lamp includes a glass bulb with a tungsten filament.

• The structure of an incandescent lamp consists of a glass bulb with an aluminum filament.

• An incandescent lamp is made of a metal bulb with a silver filament.

• The structure of an incandescent lamp includes a plastic bulb with a copper filament.

How does an incandescent lamp produce light?

• By reflecting sunlight through a lens.

• By heating up a gas inside the bulb.

• By using a fluorescent coating on the inside of the bulb.

• By passing an electric current through a tungsten filament.

What is the purpose of the filament in an incandescent lamp?

• To cool down the lamp

• To increase the lamp's weight

• To produce light

• To emit a fragrance

Explain the role of the glass bulb in an incandescent lamp.

• The glass bulb is designed to emit a specific color of light.

• The glass bulb is used to enhance the brightness of the light emitted.

• The glass bulb is responsible for regulating the electrical current in the lamp.

• The glass bulb protects the filament and maintains a vacuum or inert gas environment.

What gases are present inside an incandescent lamp?

• Carbon dioxide and neon

• Argon and nitrogen

• Oxygen and helium

• Krypton and xenon

What is the function of the base in an incandescent lamp?

• Regulate the flow of electricity

• Hold the glass bulb in place

• Enhance the color of the light

• Provide electrical connections to the filament

Why is a vacuum or inert gas used inside an incandescent lamp?

• To increase the brightness of the filament

• To add color to the light emitted

• To reduce the cost of production

• To prevent the filament from oxidizing and burning out.

How does the tungsten filament contribute to the operation of an incandescent lamp?

• The tungsten filament reflects light to illuminate the lamp.

• The tungsten filament absorbs light when heated by electricity.

• The tungsten filament emits light when heated by electricity.

• The tungsten filament conducts electricity to produce light.

Discuss the heat dissipation in an incandescent lamp.

• Heat dissipation in an incandescent lamp is caused by the presence of water inside the bulb.

• Heat dissipation in an incandescent lamp is due to the use of a cooling fan within the bulb.

• Heat dissipation in an incandescent lamp is primarily due to the filament heating up and emitting heat energy into the surroundings.

• Heat dissipation in an incandescent lamp is a result of the bulb absorbing heat from the surroundings.
