हिन्दी

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): In a series combination of unequal capacitors connected across a DC voltage source, the potential difference across the smallest capacitor is the maximum. Reason (R): In a series combination of capacitors, each capacitor carries the same charge \( Q \). 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

In series, charge \( Q \) is identical on all capacitors. Since \( V = Q/C \), the capacitor with the smallest \( C \) has the largest potential drop \( V \). (R) is the direct reason for (A).
