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.

Ideal voltage sources and ideal current sources, while both being sources of electrical power, behave very differently from one another. Voltage sources Current sources V Explain how each type of electrical source would behave if connected to a variable- resistance load. As this variable resistance was increased and decreased, how would each type of source respond?
