Assertion (A): Two condensers of same capacity connected first in parallel and then in series. The ratio resultant capacities in the two cases will be (4: 1 ). Reason (R): In parallel combination, equivalent caps Let increases and in series equivalent capacity decreases.

Options

  1. AIf both Assertion (A) and Reason (R) are True and the Reason ( (R )) is a correct explanation of Assertion (A)
  2. BIf both Assertion (A) and Reason (R) are True but Reason (( R ) ) is not a correct explanation of the Assertio
  3. CIf Assertion (A) is True but the Reason (R) is False.
  4. DAssertion (A) is False but the Reason (R) is True.

Correct answer

B. If both Assertion (A) and Reason (R) are True but Reason (( R ) ) is not a correct explanation of the Assertio

Step-by-step solution

For parallel combination (C_ eql =C+C=2 C ) For series combination ( aligned & 1 C_ eq q₀ = 1 C + 1 C & C_ eq q₀ = C 2 aligned ) Ratio of resultant capacities ( C_ e q₁ C_ e q₀ = 2 C^ C^ 12 = 4 1 =4: 1 )
