NEET 2026 Physics, question 36
Question 36 of the NEET 2026 paper (re-exam) is a Physics question from Current Electricity. Its idea, Temperature Dependence, was asked twice, in 2023 and 2026, across NEET 2017–2026. The NTA final answer key gives option 1.

Q36 · Physics
Consider two circuits, (A) and (B), each having two resistors. One of them has a positive temperature coefficient of resistance, , while the other one has a negative temperature of coefficient, , as shown in the figure. The current through these circuits are denoted by and . At initial temperature, the resistance of the two resistors is . As the temperature is increased, the correct option that describes the variation of current in these circuits is :
The figure, described in words
Circuit (A): battery V with R0(1-alpha dT) and R0(1+alpha dT) in series; circuit (B): the same two resistors in parallel across battery V.
