Question
I ONLY NEED HELP WITH d) so only solve d please.
Two identical resistors are connected in series and then connected to a 20.0 V
source potential. Initially at 20°C, the current is measured to be 0.300 A.

a) After a substantial amount of time has passed, the current is found to have
dropped to 0.275 A. What must be the operating resistance of the individual
resistors at this time?

b) If the temperature coefficient of resistivity of the material composing the
identical resistors is 2.40 x 10-3 °C-1, what temperature are they operating at
regarding part (a)?

c) If the two identical had been configured in parallel and then connected to the
20.0 V source potential, what amount of power would they have initially drawn at
20°C?

d) If both the series and the parallel configurations draw the same amount of total
power at their respective operating temperatures, at what temperature does the
parallel configuration operate?
