Let’s go through each question step by step.

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

Looking at the diagram:

- X is connected to the battery — it’s the power source. So, X = Battery
- Y is a switch (you can see the lever that opens or closes the circuit). So, Y = Switch
- Z is the wire connecting everything together. 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’re matching statements to X, Y, or Z.

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

ii. Path for electrons to flow → Electrons flow through wires → Z

iii. Opens or closes the circuit → That’s what a switch does → 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, the circuit becomes complete. Electricity can now flow from the battery, through the wire, through the switch, and into the light bulb. The bulb lights up because electricity is flowing through it.

✔ 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 electron flow are called insulators.

Examples: rubber, plastic, glass.

✔ Answer: Insulator

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

Options:
a. Plastic → insulator
b. Glass → insulator
c. Cooper → likely meant “Copper” → metal, great conductor!

Even though it says “Cooper”, we assume it’s a typo for “Copper”.

✔ Answer: c. Cooper (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 he works with electricity, wearing rubber gloves protects him from getting electric shocks.

✔ Answer:
Mr. Smith wears rubber gloves because rubber is an insulator and stops electricity from flowing through his body, keeping him safe from electric shocks.

Final Answer:

1.
X – Battery
Y – Switch
Z – Wire

2.
i. X
ii. Z
iii. Y

3. The light bulb turns on because the circuit is complete and electricity flows through it.

4. Insulator

5. c. Cooper

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