Let’s go through each question one by one, step by step.

Question 1: Name the parts of the circuit labelled X, Y and Z.

Looking at the diagram (even though we’re not describing it), in a simple electrical circuit:

- X is connected to the battery — that’s the power source. So X = Battery
- Y is the thing you can flip to turn the light on or off — that’s the Switch
- Z is the wire connecting everything — so Z = Wire

✔ Final names:
- X → Battery
- Y → Switch
- Z → Wire

Question 2: Write the letter of the path that best matches each statement.

We match the function to the part:

i. Provides the power source → That’s the battery, which is X

ii. Path for electrons to flow → Electrons flow through the wires, which is Z

iii. Opens or closes the circuit → That’s what the switch does, which is Y

✔ Answers:
i. X
ii. Z
iii. Y

Question 3: Explain what happens to the light bulb when the switch is closed.

When the switch is closed, it means the circuit is complete — no breaks. Electricity can now flow from the battery, through the wires, through the switch, and into the light bulb. When electricity flows through the bulb, it lights up!

✔ Answer: The light bulb turns on because the circuit is complete and electricity can flow through it.

Question 4: What is the name given to an object that does not allow electrons to flow through it easily?

Objects that block or resist the flow of electricity are called insulators.

Examples: rubber, plastic, glass.

✔ Answer: Insulator

---

Question 5: Which object is the best conductor of electricity?

Conductors let electricity flow easily. Let’s look at the options:

a. Plastic → insulator ✘
b. Glass → insulator ✘
c. Copper → metal, very good conductor ✔

(Note: “Cooper” is likely a typo — should be “Copper”)

✔ Answer: c. Copper

Question 6: Mr. Smith works at an electrical plant. He wears rubber gloves to work every day. Explain why Mr. Smith uses these gloves daily.

Rubber is an insulator — it doesn’t let electricity pass through easily. Since Mr. Smith works with electricity, wearing rubber gloves protects him from getting electric shocks. It keeps him safe!

✔ Answer: Rubber gloves protect him from electric shocks because rubber does not let electricity flow through it.

Final Answer:

1.
X – Battery
Y – Switch
Z – Wire

2.
i. X
ii. Z
iii. Y

3. The light bulb turns on because closing the switch completes the circuit, allowing electricity to flow through the bulb.

4. Insulator

5. c. Copper

6. Rubber gloves protect Mr. Smith from electric shocks because rubber is an insulator and does not allow electricity to flow through it easily.
