Question
Consider two circuits, (A) and (B), each having two resistors. One of them has a positive temperature coefficient of resistance, +a, while the other one has a negative temperature of coefficient, — a, as shown in the figure. The current through these circuits are denoted by [, and I. At initial temperature, the resistance of the two resistors is R,. As the temperature is increased, the correct option that describes the variation of current in these circuits is : \Y I, \Y I, a. R,1-0AT) R1+0AT) ’ R (1+aAT) @) ‘B®
Options
- 1I, remains constant while I; increases
- 21, decreases while I, increases
- 31, increases while I, decreases
- 4both I, and I, remain constant
