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.

Prepare a list of objects around you that are electroplated.
Which of the following metals is used in electroplating to make objects appear shining?
Electroplating of ______ is done on objects like water taps and cycle bell to give them a shiny appearance.
Paheli set up an experiment using liquid A in the beaker as shown in the following figure. She observed that the bulb glows. Then she replaced the liquid A by another liquid B. This time the bulb did not glow. Boojho suggested replacing the bulb by an LED. They observed that the LED glows. Explain.

In the circuit given as figure, Boojho observed that copper is deposited on the electrode connected to the negative terminal of the battery. Paheli tried to repeat the same experiment. But she could find only one copper plate. Therefore, she took a carbon rod as negative electrode. Will copper still be deposited on the carbon rod? Explain your answer.
