Homework Statement
part 1 Consider the circuit of figure G, where R1=20 ohms R2=10 ohms X1=37.7 ohms X2=-53.1 ohms. Compute the current and the phase angle between the current and the applied voltage. In the figure R1 is in series with X1 and R2 and X2 are in series. R1 and X1 are in parallel with R2 and X2. X1 is an inductor and X2 is a capacitor.
part 2 determine the values of L and C from the first part.
Homework Equations
phase angle= arctan((XC-XC)/R)
v=iZ
XL=2Pi*f*L
XC=1/(2Pi*f*C)
Z= R+jX where j is the square root of -1
The Attempt at a Solution
. [/B]I feel like the problem is missing something like voltage or frequency but maybe I am just forgetting how to get this from the information given.
I think but am not sure that the phase angle would be 85.8 degrees because of arc((37.7--53.1)/(6.66))=85.8 degrees. (1/10ohms+1/20)^-1=6.66 ohms
