In the circuit of, let i represent the current out of the positive terminal of the source vI . (a) Sketch and label i versus vI over the range 210 V # vI # 110 V. Show all breakpoints and slopes. (b) Repeat if an additional resistance R4 5 5 kV is connected between the node labeled vI and the node labeled vO. Hint: exploit the fact that circuit’s behavior for vI , 0 is symmetric of that for vI . 0.
