Final answer:

Connecting bulbs in parallel offers independent control, prevents total blackout if one bulb fails, and allows for dimming effects by adding more bulbs in parallel.


Explanation:

Advantages of connecting bulbs in parallel:

  1. Each bulb can be controlled by a switch, giving independence in operation.
  2. If one bulb blows, the other bulbs remain unaffected due to separate paths for current flow.
  3. Adding more bulbs in parallel makes the other bulbs dimmer as they each receive the full voltage.

Parallel connections maintain consistent voltage across devices and enhance operational flexibility.
