In this problem, D2 in reveresed biase with v2. So as I know, no matter the value of v2 no current will flow through D2. isn't that true ? or there is something that I am missing ? if so please explain the problem for me.

a) To what value R must be adjusted in the following circuit to make IZ = 70 mA. Assume VZ =20 V at 65 mA and ZZ = 23 Ω. What is the Zener voltage at 70o C, if it has a positive TC of 0.08 %/oC.? b) Using a Complete diode model, find the diode current (ID), diode voltage (VD), and output voltage (Vo) for the diode circuit shown below. Given that: Vs = 20 V, RL=3 kΩ , Barrier Potential VF = 0.3 V , and r’d = 70 Ω. If the diode was reversed and IR = 200 µA, Determine the diode reverse voltage (VR)
A diode is a two-terminal, electronic device made using semiconductors that is designed to prevent current from flowing in a particular direction. The symbol is a triangle pointing in the direction that (positive) current is allowed to flow and a wall preventing (positive) current from flowing in the opposite direction: 1: A diode has two modes, "on" and "off". When "on", current flows, and when "off", no current flows. We generally view diodes as either "ideal" or "modeled", as described below. "Ideal" view of a diode + The "ideal" diode is either a short circuit or an open circuit. Specifically, when the voltage across its terminals is negative, no current flows, and when current flows, there is zero voltage across its terminals, as pictured below: Diode "Modeled" view of a diode +51 Diode V Ideal Diode "Off" i=0| + U≤0 + I Therefore, with current i and voltage v defined as shown on the left above, for an "ideal" diode: • Current i cannot be negative. Voltage v cannot be positive. .…

A 1) Consider the circuit at right, consisting of two LEDS (one red, one green), which you can model as “practical diodes" with VD= 2.0V (LEDS typically have larger VD's than ordinary Si or Ge diodes). R red green B a) If terminals A and B were connected to a DC source with voltage Vo, what would happen? (Consider applying in both polarities, i.e. +Vo and –Vo, and when VoVD...) b) If the terminals A and B were connected to an AC source with peak voltage VO, what would happen? (Consider both very low frequency: f<~1 Hz – and high-frequency cases.) c) If R = 1 k2, and both diodes have a maximum continuous power dissipation of 0.1 W and a peak inverse voltage VPIV = 20V, what is the maximum DC voltage VDCmax which can be safely applied between A and B?
