In the circuit of let RL 5 1 kV and IS 5 1 mA, and let the input be swept over the range 22 V # vI # 12 V. Sketch and label, versus vI , the current i supplied by the input source as well as the current through each diode. Show all breakpoints and slopes. Hint: exploit the fact that at all times we have i D 1 1 i D2 5 i D3 1 i D4 5 I S
