Question
Three bulbs A, B, C are connected in a circuit as shown in the following figure. When the switch is ‘ON’
Options
bulb C will glow first.
bulb B and C will glow simultaneously and bulbs A will glow after some time.
all the bulbs A, B and C will glow at the same time.
the bulbs will glow in the order A, B and C.

Solution
all the bulbs A, B and C will glow at the same time.
Explanation:
If the three bulbs A, B and C are connected in parallel in the circuit and the switch is turned on, then all of them will receive the same voltage simultaneously. This results in all the bulbs glowing at the same time.
If they are connected in series, they would all light up in the same order as the current flows, but typically, in a standard setup, parallel connection is the most common for all bulbs to glow at the same time when the switch is turned on.
