Boojho and Paheli performed experiments taking similar bulbs and cells but two different solutions A and B as shown in Fig.14.1.

They found that the bulb in the setup A glows more brightly as compared to that of the setup B. You would conclude that.

Options

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.

Answer

A

Explanation

The current through the solution in the setup B could be weak and therefore unable to make the bulb glow brightly. However, the current is strong enough through the liquid in set up A for the bulb to glow brightly.
Hence, the higher current is flowing through the circuit in setup A.
