Worked Solution

Step 1: In a series circuit, there is only one path. One break stops all current. Step 2: In a parallel circuit, there are multiple independent paths. Step 3: This allows other appliances to work even if one is switched off or broken.

Correct answer: If one bulb fuses, the others remain lit.
