1. The problem statement, all variables and given/known data If R1 = 2 Ω, X1 = 1 Ω, R2 = 2 Ω, and X2 = -2 Ω , the equivalent impedance Zeq (in ohms) at terminals a and b is: (the circuit diagram is attached to this post) a. 3 + j 0 b. 3 + j 2 c. 3 - j 2 d. 0 - j 2 e. 0 + j 2 The answer is a. I have no idea how to get the answer. I have tried to simplify the circuit but I do not think I am doing it right. 2. Relevant equations Series: Zeq = Z1 + Z2 Parallel: Zeq = (Z1*Z2)/(Z1 + Z2) Total Impedance is Z= r +jX Zc = -jXc ZL = j(XL) 3. The attempt at a solution I tried to: 1. combine R2 and and the capacitor in parallel (i think my errors occur here) i got (2+j) + (-4j/(2-2j)) 2. combine R1 and the inductor in series (i got 2 +j1) 3. combine the rest in series.
