iz in [mA] 6 ix + Device + 11 -v% in [V] 5 6 Figure P3.5a Figure P3.56
can someone show me step by step how to do this problem and explain the concepts
A device, shown in Figure P3.5a, can be modeled by a current source in parallel with a resistance. The relationship between the current through the device, iX, and the voltage across the device, vX, is given in the plot in Figure P3.5b.
a) Find a model for the device that would be valid when current is in the range
1[mA] < iX < 5[mA]. This model must have numerical values for the current and resistance, and the polarities with respect to vX and iX should be shown in a diagram.
b) A voltage source is applied across the device so that vX = 10[V]. Find the power delivered by the device in this situation.
