NEET Physics Resistance & Resistivity MCQ Question
Which of the following statements about electric circuits is correct?
The total current flowing into a junction equals the total current flowing out.
Electric potential changes must always sum to a positive value in a closed loop.
Potential difference is independent of the resistance in the circuit.
When charges are not continuously replenished, the current will continue indefinitely.
Correct Answer
Detailed Explanation
The first option is correct as it aligns with the principle that the total current at a junction is conserved, meaning it must equal the total current flowing out. This is elaborated in the context of steady currents where charge accumulation does not occur.
