Which component of a flashlight is responsible for holding all the other parts together?

• Bulb

• Plastic case

• Metal spring

• Slide switch

What is the function of the bulb in a flashlight?

• To store electrical energy

• To produce light when electricity flows through it

• To connect the positive and negative terminals

• To act as a switch

Which part of the flashlight completes the circuit when pressed or slid?

• Metal spring

• Slide switch

• Bulb

• Plastic case

What is the main role of the metal spring in a flashlight?

• To provide a path for electrical flow and hold the battery in place

• To emit light

• To insulate the circuit

• To act as a switch

Which terminal of the battery is usually connected to the metal spring in a flashlight?

• Positive terminal

• Negative terminal

• Both terminals

• Neither terminal

Which component allows the user to control the flow of electricity in a flashlight?

• Bulb

• Metal switch contact

• Slide switch

• Plastic case

What is the function of the metal switch contact in a flashlight?

• To produce light

• To connect or disconnect the circuit when the switch is operated

• To hold the batteries in place

• To insulate the circuit

Describe the role of the positive terminal in the operation of a flashlight.

• It provides a return path for the current

• It supplies electrical energy to the circuit

• It acts as a switch

• It holds the bulb in place

How does the electrical circuit in a flashlight ensure the bulb lights up?

• By providing insulation between components

• By allowing current to flow from the positive terminal, through the bulb, and back to the negative terminal

• By storing energy in the plastic case

• By disconnecting the metal spring

Explain how the slide switch and metal switch contact work together in a flashlight.

• The slide switch moves the bulb closer to the battery

• The slide switch moves, causing the metal switch contact to close or open the circuit, thus turning the flashlight on or off

• The metal switch contact stores energy for the bulb

• The slide switch insulates the circuit
