Boojho and Paheli performed experiments taking similar bulbs and cells but two different solutions A and B as shown in the figure.
 |
 |
| Boojho's Experiment | Paheli's Experiment |
| (A) | (B) |
They found that the bulb in the set up A glows more brightly as compared to that of the set up B. You would conclude that
पर्याय
higher current is flowing through the circuit in set up A
higher current is flowing through the circuit in set up B
equal current is flowing through both the circuits
the current flowing through the circuits in the two set up cannot be compared in this manner.
उत्तर
higher current is flowing through the circuit in set up A
Explanation -
Bulb in the set up A glows more brightly because higher current is flowing through the circuit in set up A, as solution AIso better conductor of electricity than that of B.
