    Limit Max
In summary: This conversation is discussing the maximum value of the output voltage (Vout) in a circuit with a diode. In summary, the output voltage is limited to a maximum of 5.7V, which is the maximum voltage that can be reached before the diode conducts and stops the voltage from going any higher. This is assuming that the diode is ideal and positively-biased. If the diode is not ideal, there is no theoretical limit on the output voltage. However, in this circuit, the output voltage can't exceed 5.7V if the diode is ideal.

Approx what is the maximum value of Vout

I don't have any idea I am just guessing but there's not enough details I think is 0 V but I am not sure.. how am I suppose to answer this??

They want the maximum output voltage, which applies to all possible input values.

I don't understand is that 5V?

Grab Vo, what if you try to force a voltage on it. (The actual forcing could be done by a source connected to Vin)

The output voltage is limited to a minimum of 5V. ?

You mean a maximum of 5V. If you go higher the diode turns on and there is a short to a voltage source that pins the voltage. Is there a diode drop involved?

Ok so is maximum ?

You can try different voltage values at the output and see how the circuit behaves.

If the diode is not ideal, then there is no theoretical limit on the output voltage due to limited positive-biased diode impedance. However, I assume that the diode is ideal and thus is positively-biased and turns once the output voltage exceeds the cathode voltage.

Does this make it any easier to understand. It's the same circuit. If Vin >> 5V the diode conducts and stops Vout going any higher.

so that means it could be 5.7 V? or more

No, it means it can't be more than 5.7V (=5V+Vf).

If Vin >> 5V current flows from Vin, through the resistor, through the diode to the +5V rail.
