For the circuit of sketch and label vO versus vI over the range 210 V # vI # 110 V. Show all breakpoints and slopes. Hint: if, starting at 0 V, you gradually increase vI , at what point will D1 go off? If instead you gradually decrease vI , at what point will D3 go off? (b) Repeat (a) if R3 is changed to 30 kV. (c) Repeat (a) if another 10-kV resistance is connected between the input and output nodes.
