Homework 5 problem 6

I inadvertently made number 6b a bit harder than I thought ...

For part b, if you are not able to prove the general result, it is sufficient to prove that a parallel combination has lower power consumption than a series combination. Full points if you can do this, five bonus points if you solve the question as asked.

If you want to prove the general result as the question asks, see HERE for a massive hint, along with smaller ones for other questions.

is the equation for Ptotal supposed to be Ptotal=(I1^2)R1 + (I-I1)^2(R2) ? in the equation on the hint sheet, that first R1 isn't there...

You are correct, I have fixed it.
