Statement-1: The equivalent resistance in series combination is larger than even the largest individual resistance.
Statement-2: The equivalent resistance of the parallel combination is smaller than even the smallest resistance.
Statement-2: The equivalent resistance of the parallel combination is smaller than even the smallest resistance.
View answer and explanation
Correct option: B
Statement-1 is true, Statement-2 is true, Statement-2 is not the correct explanation for Statement-1
Option B (Statement-1 is true, Statement-2 is true, Statement-2 is not the correct explanation for Statement-1) is correct because both statements are true, but they are independent facts about series and parallel resistances.
