Two sets A and B, of three bulbs each, are glowing in two separate rooms. When one of the bulbs in set A is fused, the other two bulbs also cease to glow. But in set B, when one bulb fuses, the other two bulbs continue to glow. Explain why this phenomenon occurs.

Text Solution

Verified by Experts

The bulbs of set A are connected in series. Therefore, when one bulb is fused the current stop flowing.
Whereas, the bulbs of set B are connected in parallel. When one bulb fuse, then current flows through the other bulbs.
