Find the equivalent resistance for the infinite network shown in Figure P2.12(a). Because of its form, this network is called a semi-infinite ladder. [Hint: If another section is added to the ladder as shown in Figure P2.12(b), the equivalent resistance is the same. Thus, working from Figure P2.12(b), we can write an expression for Req in terms of Req.Then, we can solve for Req.

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.
