Consider the voltage-regulator circuit shown in Figure 2. The ac ripple voltage is 1 V
peak to peak. The dc (average) load voltage is 5 V. What is the Q-point current in the
Zener diode? What is the maximum dynamic resistance allowed for the Zener diode if the
output ripple is to be less than 10 mV peak to peak?

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor
