हिन्दी

Given below are two statements:\n Statement I: The potential difference across the terminals of a cell in a closed circuit is greater than its emf when it is being charged.\n Statement II: When a cell is being charged, current enters its positive terminal and the terminal voltage equation becomes \( V = \varepsilon + Ir \). \nIn the light of the above statements, choose the most appropriate answer from the options given below:

  1. A
    Both Statement I and Statement II are correct.
  2. B
    Both Statement I and Statement II are incorrect.
  3. C
    Statement I is correct but Statement II is incorrect.
  4. D
    Statement I is incorrect but Statement II is correct.
View Answer & Solution

Correct answer · Option A

Both Statement I and Statement II are correct.

Explanation

During charging, current flows opposite to discharging, making terminal voltage \( V = \varepsilon + Ir \), which exceeds the emf \( \varepsilon \).
