A linear 2-port network is shown in Fig. (a). An ideal DC voltage source of 10 V is connected across Port 1. 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 V 2 versus -I 2 plot. Note that for V 2 = 5 V, I 2 = 0 mA, and for V 2 = 4 V, I 2 = −4 mA. When the variable resistance R at Port 2 is replaced by the load shown in Fig. (c), the current I 2 is _______ mA (rounded off to one decimal place).

A linear 2-port network is shown in Fig. (a). An ideal DC voltage source of 10 V is connected across Port 1. 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 = 5 V, I₂ = 0 mA, and for V₂ = 4 V, 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).
