Homework Answers
Answer: Option - A ( Circuit -1 )
Explanation:
The parallel combination of a bulb resistances are reduces the effective resistance of the circuit. The voltage across the each bulb resistance is the same as the applied battery voltage.Hence most of the supplied voltage ( the electrical energy ) reaches the bulb. Hence it glows brighter
