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

Question 1:
*This circuit has more than one loop. When one light goes out, the others stay on.*
We know that in a
parallel circuit, there are multiple paths (loops) for electricity to flow. So if one bulb burns out or is removed, the other bulbs still have their own path and keep working.
In a
series circuit, all components are in one single loop — so if one bulb goes out, the whole circuit breaks and everything turns off.
“Closed circuit” just means the circuit is complete and working — it doesn’t tell us about loops or what happens when a bulb goes out.
“Open circuit” means the circuit is broken — nothing works at all.
So the correct answer is:
parallel circuit

Question 2:
Looking at the diagram: The battery connects to a switch, then to three bulbs stacked vertically — but they’re connected end-to-end in a single line. That means current flows from the battery → switch → first bulb → second bulb → third bulb → back to battery. Only ONE path.
That’s the definition of a
series circuit.
Even though the bulbs are drawn vertically, they’re still wired one after another — no branches.
Answer:
series

Question 3:
The diagram shows a battery, a switch (which is OPEN — you can see the gap), and a bulb. Since the switch is open, the circuit is not complete. Electricity cannot flow.
So this is an
open circuit.
“The cutest little circuit evah!” is funny, but not a real type of circuit 😊
Answer:
open

Question 4:
“When all parts of the circuit are connected it is a ___ circuit.”
If everything is connected properly and electricity can flow, we call that a
closed circuit.
An “open circuit” means something is disconnected or broken.
Answer:
closed

Question 5:
The picture shows two bulbs connected one after another in a single loop with a battery. There’s only one path for current to take — through both bulbs.
That’s exactly what makes a
series circuit: components are connected in a single path, one after another.
So the reason it’s a series circuit is because:
there is only one path for the electric current to follow.
*(Note: Since the full options aren’t shown, based on standard knowledge, this is the correct reasoning.)*

Final Answer:
1. B
2. B
3. A
4. B
5. [There is only one path for the electric current to follow.]
