# R-C network analysis (AC)

**1. The problem statement, all variables and given/known data**

Compute values for R and C such that the total series impedance Z=500[itex]\angle[/itex](-36.1^{o}) when f=10kHz.

**2. Relevant equations**

ω=2[itex]\pi[/itex]f

KVL

Z_{C} = -j*(1/(ωC)) = 1/(jωC) where j=[itex]\sqrt{-1}[/itex]

**3. The attempt at a solution**

Seems like a pretty straightforward problem, I seem to be missing an equation somewhere but not sure what else I could use here.

ω=2*[itex]\pi[/itex]*10*10^{3} = 62832 rad/s

Z_{eq}=500[itex]\angle[/itex](-36.1^{o}) = R – j/(ωC) = R – j/(62832*C)

And here I am left with 1 equation and 2 variables, any ideas on what else I could use to solve this problem?
