10.2: OPEN CIRCUIT IMPEDANCE OR [Z] PARAMETERS Engineering360

[Z] parameters are known as open circuit impedance parameters because, in both the cases, one port is open (i.e., I 1 = 0 and I 2 = 0) Z 11 and Z 22 are drivingpoint impedance at port 1 and port 2. In the case of drivingpoint function the data should be from the same port.

Understanding resistance in open and short circuits

Understanding resistance in open and short circuits

In circuit C the current sees a short across the right most resistor, the current will prefer to go through that short to complete the circuit. Thus you get 12/2 = 6A Infinite resistance is the same like saying the resistor isn't connected at all, since no current can flow though it V/infinity = 0.
