linear 2-port network is shown in Fig. (a). An ideal DC voltage source of  is connected across Port 1. A variable resistance  is connected across Port 2. As  is varied, the measured voltage and current at Port 2 is shown in Fig. (b) as a  versus  plot. Note that for , , and for .

When the variable resistance  at  ort 2 is replaced by the load shown in Fig. (c), the current  is _________  (rounded off to one decimal place).
