AIIMS 2019 Physics Equivalent Resistance MCQ Question

Option C is correct because it accurately describes the behavior of the circuit under the given conditions, demonstrating the principles of Ohm's Law (V = IR) and Kirchhoff's circuit laws. The other options are incorrect as they either misinterpret the voltage or current relationships in the circuit or fail to account for the effects of resistance on the overall circuit behavior. Understanding these fundamental concepts is crucial for analyzing electrical circuits and predicting their performance.
