Apparently the last part for Power is wrong. I tried with Vpeak, Vrms and still something is not right. The professors tells me something about the resistance not being completely right and needing to do a thevenin equivalent.



I would appreciate any help. I'd been thinking about this for the past 2 days and I can't figure out what's wrong with the last part.
