The given diagrams show three different circuits. In each circuit, similar batteries and bulbs of the same wattage are used. When the electric circuits are connected, all the bulbs light up.

Which of the following options is true about the bulbs 1, 2 and 3?

Text Solution

Verified by Experts

The correct Answer is:
B
Brightness of the bulb depends upon the current flowing through the bulb.
In circuit (1 ), the current flowing is maximum, whereas in (3), the resistance is maximum. The descending order of brightness is 1, 2 and 3.
