Series and parallel circuit interactive worksheet - Free Printable

I need to determine whether each of the six circuits is a series circuit or a parallel circuit. Let me examine each one carefully.

First, I'll recall the definitions:
- In a series circuit, components (like bulbs) are connected one after another in a single path. The current flows through each component in turn.
- In a parallel circuit, components are connected across common points, creating multiple paths. Each component has its own separate path from the power source.

Now I'll analyze each circuit:

1. Circuit 1: I see two bulbs. Wires connect from the battery to a switch, then split to go to each bulb separately, and then rejoin before returning to the battery. This means each bulb has its own path → Parallel circuit.

2. Circuit 2: Two bulbs are connected one after another in a single loop: battery → switch → bulb 1 → bulb 2 → back to battery. Only one path for current → Series circuit.

3. Circuit 3: Similar to circuit 2 — battery → bulb 1 → switch → bulb 2 → back to battery. One continuous path → Series circuit.

4. Circuit 4: Battery connects to a switch, then wires split to go to each bulb separately, and then join again before returning to battery. Two separate paths → Parallel circuit.

5. Circuit 5: Three bulbs are connected one after another in a single line: battery → switch → bulb 1 → bulb 2 → bulb 3 → back to battery. One path only → Series circuit.

6. Circuit 6: Battery → switch, then wires split to each of two bulbs, and then rejoin before returning to battery. Two separate paths → Parallel circuit.

Let me double-check by zooming in on any ambiguous ones.
