Question 2
Boojho and Paheli performed experiments taking similar bulbs and cells but two different solutions A and B as shown in Fig.
They found that the bulb in the setup A glows more brightly as compared to that of the setup B. You would conclude that
(a) Higher current is flowing through the circuit in setup A.
(b) Higher current is flowing through the circuit in setup B.
(c) Equal current is flowing through both the circuits.
(d) The current flowing through the circuits in the two setups cannot be compared in this manner.
The answer is (a).
Bulb in the set up A glows more brightly because a higher current is flowing through the circuit in set up A, as solution A is a better conductor of electricity than that of B.
