Two Electrical Resistors with Resistances R₁ and R₂ (In Ohms)

question 42

Multiple Choice

Two electrical resistors with resistances R₁ and R₂ (in ohms) are wired into an electronics circuit as shown in the figure below. The pair of resistors behaves as a single resistor R_T whose resistance is given by . Once the circuit is energized, the temperatures of the resistors increase, causing the resistances to increase according to: , , where t is in seconds. Find .
