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).
