Question

15. If the air surrounding a charged conductor is changed by other insulating medium, its
a) Capacity increases
b) Capacity decreases
c) Capacity does not change, d) Capacity becomes zero
​

Answer 1

Answer:

capacity increases

Explanation:

Since the charged conductor induces opposite charge on the near face of the isolated conductor, which moves the charges of the conductor towards it making it draw more charge from the source where it is connected. Hence the capacity of a conductor is affected due to the presence of an uncharged isolated conductor.

Since the presence of a dielectric medium induces additional charges into the conductor, the conductor can hold more charge at the same potential

Answer 2

Answer:

a) Capacity increases

Explanation:

a) Capacity increases

Due to the opposing charge that the charged conductor produces on the isolated conductor's near face, which draws the conductor's charges closer to it and increases the amount of charge it draws from the linked source, Therefore, the existence of an isolated, uncharged conductor reduces a conductor's capacity.

The conductor may store more charge at the same potential because the presence of a dielectric medium creates more charges in it.

Free electrons, also known as conduction electrons, which are electrons in a substance that are not bonded to an atom, are subject to forces if an electric field is present within a conductor. The liberated electrons then pick up speed. Contrary to our belief, however, moving charges by definition imply nonstatic situations.
