Question
These lamps are connected in parallel circuits. One of the lamps breaks.
Which circuit correctly shows the effect this has on the other lamps in the circuit.
- A
- B
- C
- D
Hint:
In parallel connection each branch is independent of other branches.
The correct answer is: D
- The bulbs are connected in parallel hence the current is divided in each branch.
- The current keeps flowing to other branches if one of the branches is broken.
- Hence all other bulbs will keep working after unscrewing of bulb 2.
