I am trying to solve the questions from the link above. I need a clarification on how to find the impedence angles
Question #6.) This one I can solve OK
XL=942.48Ω
Z=1771.5Ω
R-parallel=2092Ω
X-parallel=3329.74Ω
therefore
L=1.326H
Zt=1771.5Ω
θ=tan^-1(R/XL)=32.14 degrees
Question #7.)
Xc=1178.93Ω
Z=1066.55Ω
R-series=455Ω
X-series=964.88Ω
therefore
C=3.29uF
Zt=1066.55Ω
θ=tan^-1(Xc/R)=64.75
the only reason I was able to find θ on question #7 is because I looked at the answer, then tried to figure out what method they used to get it. But why is...
Question #6.)θ=tan^-1(R/XL)
and
Question #7.)θ=tan^-1(Xc/R)
what is the correct method in finding the angles?
