Statement-1: Two unequal resistances are connected in series across a cell, then potential drop across the larger resistance is more.
Statement-2: The current will be same in both unequal resistances.
Statement-2: The current will be same in both unequal resistances.
View answer and explanation
Correct option: A
Statement-1 is true, Statement-2 is true, Statement-2 is the correct explanation for Statement-1
Option A (Statement-1 is true, Statement-2 is true, Statement-2 is the correct explanation for Statement-1) is correct because in a series circuit, the current is the same through all resistors, and the potential drop is proportional to the resistance.
