Consider two circuits, (A) and (B), each having two resistors.
One of them has a positive temperature coefficient of resistance, \(+\alpha\), while the other one has a negative temperature coefficient of resistance, \(-\alpha\), as shown in the figure.
The current through these circuits are denoted by \(I_A\) and \(I_B\).
At initial temperature, the resistance of the two resistors is \(R_0\).
As the temperature is increased, the correct option that describes the variation of current in these circuits is:
