Consider the two-port resistive network shown in the figure. When an excitation of 5 V is applied across Port 1, and Port 2 is shorted, the current through the short circuit at Port 2 is measured to be 1 A (see (a) in the figure). Now, if an excitation of 5V is applied across Port 2 and Port 1 is shorted (see (b) in the figure), what is the current through the short circuit at Port 1?
