Boojho and Paheli performed experiments taking similar bulbs and cells but two different solutions A and B as shown in the following figure.
 |
 |
| Boojho's Experiment | Paheli's Experiment |
| (A) | (B) |
They found that the bulb in the setup A glows more brightly as compared to that of the setup B. You would conclude that
विकल्प
higher current is flowing through the circuit in setup A
higher current is flowing through the circuit in setup B
equal current is flowing through both the circuits
the current flowing through the circuits in the two setups cannot be compared in this manner.

उत्तर
higher current is flowing through the circuit in setup A
Explanation:
Bulb in the setup A glows more brightly because higher current is flowing through the circuit in setup A, as solution Also better conductor of electricity than that of B.
