I have a few questions from the Camera Power Practice Problems Book.
1.) Chapter 27, problem 7 and 8:
Problem 7: Why does the solution manual tell you to use "rms values"? The reference book shows to solve the power triangle differently.
Problem 8: So what does it mean when Q=0? Does this mean S=P?
2.) Chapter 28, Problem 7: Where does the equation Z=sqrt*((sumR)^2+(sumXL - sumXC)^2) come from? I didnt see it at all in Camera's reference book.
3.) Chapter 29, problem 9(B): Any reason why the solution to the current equation i(t) reduces to 0.625 + (.2926...)?
Any help on these problems would be greatly appreciated.
Thanks!!
