Eletricity - series and parallel circuit worksheet - Free Printable

Explanation:
We need to identify whether each circuit is a series circuit or a parallel circuit.

🔹 In a series circuit, all components (like bulbs) are connected one after another in a single path. The current flows through each component one at a time. If one bulb burns out, the whole circuit breaks and all bulbs go off.

🔹 In a parallel circuit, components are connected across multiple paths (branches). Each bulb has its own separate path to the battery. If one bulb burns out, the others stay on.

Now let’s analyze each diagram:

1. Three bulbs connected end-to-end in a single loop with the battery and switch → Series
2. Each bulb has its own separate branch from the main wire (wires split and rejoin) → Parallel
3. Bulbs stacked vertically, each connected top-to-bottom in one continuous path → Series
4. All three bulbs share the same two connection points (left side all connected together, right side all connected together) → Parallel
5. Two bulbs connected side-by-side, each with its own wire path from battery → Parallel
6. Two bulbs connected one after another in one loop → Series
7. Two bulbs: wires split after the battery, each bulb gets its own path, then wires join again → Parallel
8. Two bulbs connected one after another in a single loop with battery and switch → Series

Let me double-check each:
- #1: Yes, single path — series.
- #2: Each bulb has independent connections — parallel.
- #3: No branching — series.
- #4: Clear parallel branches — parallel.
- #5: Two separate loops from battery — parallel.
- #6: One path only — series.
- #7: Branching before bulbs — parallel.
- #8: One continuous loop — series.

All correct.

Final Answer:
1. Series
2. Parallel
3. Series
4. Parallel
5. Parallel
6. Series
7. Parallel
8. Series
