1. The problem statement, all variables and given/known data Determine the equivalent impedance of the following network: [Broken] (My bad, the element at the far right where the j2ohm is was supposed to be an inductor, fixed now. The numbers are correct too.) 2. Relevant equations R(series) = R1 + R2? R(parallel) = [ (1/R1) + (1/R2) ]-1 except with impedance now 3. The attempt at a solution Not sure if I can do algebra with the imaginary components... but the right branch would simplify to (4Ω - j4Ω/3) Then this is in parallel with j4Ω, simplifying to (12Ω + j4Ω + j12Ω)/(j4Ω(12Ω - j4Ω)). All I want to know, is if this is really the right track? Can I really algebraically manipulate the imaginary components like this (maybe I Just need to review algebra now)? Any other tips would be helpful, thanks.
