Question

Three light bulbs are connected to a battery in a series circuit. How will the bulbs behave if the circuit is closed?

Answer 1

all three will glow A

Answer 2

Answer: The correct answer is "All three bulbs will glow".

Explanation:

In the series combination of the circuit, the same current flows across the conductor  in the circuit. But the voltage is different in the series combination.

In the parallel combination, the different current flows across the conductor in the circuit. But the voltage is same in the parallel combination of the circuit.

In the given problem, three light bulbs are connected to a battery in a series circuit. If the given circuit is closed then all bulbs connected in the circuit will glow as the same current will flow in three bulbs.

Therefore, the correct option is (A).
