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 . Reason (R): In parallel combination, equivalent caps Let increases and in series equivalent capacity decreases.
Options
- AIf both Assertion (A) and Reason (R) are True and the Reason () is a correct explanation of Assertion (A).
- BIf both Assertion (A) and Reason (R) are True but Reason ((\mathrm{R})) is not a correct explanation of the Assertion (A).
- CIf Assertion (A) is True but the Reason (R) is False.
- DAssertion (A) is False but the Reason (R) is True.
Correct answer
B. If both Assertion (A) and Reason (R) are True but Reason ((\mathrm{R})) is not a correct explanation of the Assertion (A).
Step-by-step solution
For parallel combination
(C_{\mathrm{eql}}=C+C=2 C)
For series combination )
Ratioresultant capacities (\Rightarrow \frac{C_{e q_1}}{C_{e q_0}}=\frac{2 \not C^{\prime}}{C^{\prime} 12}=\frac{4}{1}=4: 1)$
For series combination )
Ratioresultant capacities (\Rightarrow \frac{C_{e q_1}}{C_{e q_0}}=\frac{2 \not C^{\prime}}{C^{\prime} 12}=\frac{4}{1}=4: 1)$
