Clarification: In constant voltage drop model at forward bias diode can be replaced as a cell and in reverse bias diode can be avoided by considering the terminals are open. Since D1 is in forward biased there will be a voltage drop of 0.5V. So net voltage will be 2.5V and hence current is 2.5mA. 4.Whenever diode is forward biased, output voltage is 0.7V due to the constant voltage drop model. When the diode is reverse biased, the complete input 5sint – 1 is observed at the output side. So the output lies between 0.7V to 5sint-1V, i.e a maximum of 4V.Question: For each of the circuits given below, assume that the diodes are following a constant voltage drop model with Von=0.75 V.

The lab that he is doing specifies the use of the constant-voltage-drop model for the diode with a forward drop of 0.7 V. The whole point of the lab is to hit home the point that even with that model, you can't just blindly assume that the voltage drop across the diode is always a constant 0.7 V.Simple answer is that diode can't act as a voltage source. If external voltage (Vext) is greater than 0.7V then drop across diode is 0.7V and if Vext < 0.7V then the drop across the diode can't be greater than Vext.
