Question 1

What are the open-circuit reverse voltage gain and the short-circuited forward current gain respectively for the two-port network shown in the figure?

Question 2

What are the open-circuit transfer admittance and the negative short-circuit current ratio respectively for the two-port network shown in the figure?

Question 3

A linear 2-port network is shown in Fig. (a). An ideal DC voltage source of 10 V is connected across Port A variable resistance R is connected across Port 2. As R is varied, the measured voltage and current at Port 2 is shown in Fig. (b) as a V2 versus -I2 plot. Note that for V2 = 5V, I2 = 0 mA, and for V2 = 4V, I2 = − 4 mA

When the variable resistance 𝑅 at Port 2 is replaced by the load shown in Fig. (c), the current I2 is _______ mA (rounded off to one decimal place).
