Question

Gargi was checking whether the following materials can conduct electricity: wood, thread, plastic.

Is this experiment sufficient to conclude that all the 3 materials do not conduct electricity?

A.Yes, since the bulb didn't glow for any of the three materials.
B.No, since she did not use all the three objects at the same time.
C.No, since she also needs to check if the bulb glows or not when we touch P to Q directly.
D.Yes, since only the switch was changed while the other circuit components remained the same.

Answer 1

Answer:

The answer is option (c)[This experiment is not sufficient] because without completing the circuit we could not get the result.Though we know that the 3 materials(given in the question) are insulaters of the electricity.But according to the question we have to find the nature of the 3 materials of conductivity through experiment.So..... option (c)
