Roughly, 200m mV.
Consider ideal diode to be connected in series with resistor of 6kSilicon diode forward bias voltage = 0.7 voltsCurrent across 6k resistor = (5-0.7)/6000 amperesVoltage across {resistor + diode}=4.3 + 0.7=5vIf silicon internal resistance is 6k then voltage across diode=5vIf external resistance is 6k and diode resistance is negligible then voltage across diode=0.7v
A: Both diodes have the same curve in the forward direction however if the zener voltage is reverse it will breakdown at a particular voltage and remain conducting at the voltage. A regular diode will not do that the to voltage will fold back after breakdown to any voltage
About 0.2V
There is no exact substitute for a germanium diode, except another germanium diode. However if the only concern is to get a lower forward voltage drop than that of a silicon diode (0.7V), then a schottky barrier diode may be a suitable replacement as its forward voltage drop (<0.1V) is even lower than that of a germanium diode (0.2V).
To be forward biased any diode (e.g. vacuum tube, crystal, junction, point contact) must have its relative anode voltage more positive than its cathode voltage. If the absolute anode voltage is negative but the cathode voltage is even more negative, then the diode will be forward biased. But as your question made no mention at all of the cathode, I cannot tell if this is the case or not.
The 1N34 is a germanium signal diode, so it would be used as a detector/mixer in a.m. reception for example.
there is no forward breakdown voltage for any diode
0.7 The voltage across a silicon diode when it is forward biased should be greater than or equal (>=) 0.7volts.
That depends on the zener voltage rating:"low voltage" zeners are just a simple single diode, the zener diode"high voltage" zeners contain 2 back to back diodes in one package, the zener diode and an ordinary diode that is reverse biased when the zener diode is forward biased to block forward conduction of the zener and protect it from overcurrent damage if installed backwards by mistakeThus in "low voltage" zeners when forward biased they will have a normal diode drop (e.g. 0.7V), but "high voltage" zeners when "forward biased" they will act open due to the reverse biased blocking/protection diode in series with the zener.
If the applied voltage is greater than maximum forward voltage, the diode will get damaged..
The diode conducts at its forward breakdown voltage. Depending on the current, and the type of diode, the voltage could be anywhere between 0.2 and 3.5 volts, with a nominal silicon range of 0.7 to 1.4.
DC forward voltage is generally related to diodes. It means the voltage across the diode when the diode is forward biased, i.e. when the anode is more positive than the cathode. The forward voltage is the drop across the diode. The amount of drop is a function of current. For typical silicon diodes, the forward voltage drop ranges from 0.6 volts for very small currents, to 1.5 or more volts for large currents.

Yes, the forward voltage drop of a Schottky diode is usually more than the forward voltage drop of a tunnel diode. A Schottky diode voltage drop is between approximately 0.15 to 0.45 volt. The interesting thing that makes a tunnel diode different from other diodes is its "negative resistance region" with a "peak current" around 0.06 volt and a "valley current" around 0.30 volt.
The current is nearly zero at a voltage less than 0.4v in a forward biased silicon diode because of the small forward-bias voltage.

forward drop is the same as any other silicon diode, about 0.7V
