Answer 1

Procedure step: (1): open the load terminals and find voltage across it. Step (2): voltage source implies short circuit current source implies open circuit} find z_n 1_1 = -4 rightangle 0 degree, 1_2 = 7 rightangle 0 degree, 1_3 - 7 rightangle 0 degree I = i_1 - i_2 = -4 rightangle 0 degree - 7 rightangle 0 degree = -4 + j o - 7 + j o = -11 rightangle 0 degree I^1 = i_2 - i_3 = 7 rightangle 0 degree - 7 rightangle 0 degree = 0 \r\n + v + 22 rightangle 90 degree - 8 rightangle 90 degree v = 22 rightangle 90 degree - 8 rightangle 90 degree = j 22 - j 8 = j 14 = 14 rightangle 90 degree + 14 rightangle 90 degree + 22 rightangle 90 degree - 14 rightangle 0 degree + v_Th = 0 v_th = j 14 + j 22 - 14 v_th = -14 + j 36 z_ th current source open...
