Refer to the following circuit. Apply Wye - Delta transformation or any other method, to find the voltage VAB. E 120 20°V 60Hz 2 Z₁ 0004 Z₁ 20 6500 A Z₂ 50 Zs 110 ZA 60 Z₂ 330 x Z₂ 30 90 Za 16.50 B

b) a) For the circuit shown in figure 3, use nodal analysis to obtain a complete set of circuit equations, presenting your answer in matrix form. Compute the potential across and the current flowing through the ZL element, given: IS = 12sin(wt) A, R1 = 3 0, R2 = 50, L1=j4Q, L2=j10 Q and ZL = (2+j2) Q IS R1 m L2 R2 ZL Figure 3 Using equations and text, define the two-port impedance parameters.
