Consider the circuit obtained from that of by reversing the diode direction so that the anode is now at the right and the cathode at the left. Let vS 5 4 V, R1 5 2 kV, R2 5 3 kV, R3 5 1 kV, and iS 5 4 mA. Assuming the diode has Is 5 20 fA and nVT 5 35 mV, fi nd the diode voltage (in mV) and the diode current (in A), as well as the voltage v across the current source and the current i through the voltage source. Use both the iterative method and the 0.7-V diode model, compare the results, comment.
