Physics · Electrostatic Potential

हिन्दी

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): To store a large amount of charge on a capacitor without sparking, the capacitor should have a large capacitance. Reason (R): A large capacitance ensures that for a given charge \( Q \), the potential difference \( V \) and the resulting electric field remain below the dielectric breakdown limit of the medium. In the light of the above statements, choose the correct answer from the options given below:

  1. Both (A) and (R) are true and (R) is the correct explanation of (A).
  2. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
  3. is true but (R) is false.
  4. is false but (R) is true.

Correct answer · Option 1

Both (A) and (R) are true and (R) is the correct explanation of (A).

Explanation

Since \( V = Q/C \), a large \( C \) keeps \( V \) and the surrounding electric field small for a given \( Q \), preventing the air from ionizing and discharging. Thus, Reason correctly explains Assertion.
