Q1:

The Z parameters Z11 and Z21 for the 2-port network in the figure.

A Z11 = - 6/11Ω; Z21 = 16/11Ω

B Z11 = 6/11Ω; Z21 = 4/11Ω

C Z11 = 6/11Ω; Z21 = - 16/11Ω

D Z11 = 4/11Ω; Z21 = 4/11Ω

ANS:C - Z11 = 6/11Ω; Z21 = - 16/11Ω

Apply mesh analysis in both loop 11E1 = 6I1 + 4I2, E2 + 10 E1 = 4 (I1 + I2) Z21 .
