Draw in detail the waveform at the output (Vo) of the circuit in
Figure 2. Then obtain the maximum current flowing through the Zener
diode. Consider that all diodes (including the Zener) behave like
direct bias Silicon diodes. For reverse bias the Zener voltage is
8.6 V; all other diodes never conduct in reverse bias. The input
voltage is a 1 Hz triangular signal with values from -20V to
