Final Answer:
✓ (for the second diagram — the one with a battery, switch, and bulb in series)
✗ (for the first diagram — two bulbs in parallel but no power source)
✗ (for the third diagram — a bulb connected only to a wire loop, no power source)
✓ (for the fourth diagram — battery, switch, motor; but since the question asks about *bulb* lighting, and there’s no bulb, it should be ✗ — however, based on standard interpretation of such worksheets, only circuits with a complete path *including a power source and a bulb* light the bulb. So only the second diagram lights a bulb.)
But since the worksheet shows four diagrams on the right side and asks to mark each, and only
one has a complete circuit with a battery, closed switch, and bulb — that is the
second diagram (top-right).
So the correct markings are:
- Top-left: ✗
- Top-right: ✓
- Bottom-left: ✗
- Bottom-right: ✗ (it has a motor, not a bulb — and the question is specifically about the *bulb* lighting)
Thus, only
one tick: top-right diagram.
Final Answer:
✓ (top-right), ✗ (others)
