Approximate voltage across the forward-biased base emitter?
The approximate voltage across the forward-biased base-emitter junction is 0.7 volts.
How much voltage is there across a silicon diode when it is forward biased?
0.7 The voltage across a silicon diode when it is forward biased should be greater than or equal (>=) 0.7volts.
Why is the current nearly zero at a voltage less than 0.4 v in a forward biased silicon diode?
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.
What is a barrier voltage?
The voltage across a forward-biased PN junction in a semiconductor diode or transistor.
How much voltage appears across a zener diode when it is forward-biased?
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.

How much voltage is there across a germanium diode when it is forward biased?
About 0.2V
Can a silicon diode be forward biased if the anode voltage is negative?
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.
What is V-I characteristics of zener diode?
Work in reverse bias.(breakdown at a particular voltage to keep the volt. constant so used as voltage regulator) same as diode when forward biased.
When biased correctly a zener diode acts as?
a diode and it has a constant voltage across it ANSWER: acts as a voltage regulator if enough current flows to create a breakdown voltage.
What are the vi characteristics of ideal diodes?
Zero current flow when reverse biased, zero voltage drop when forward biased.
What is meant by cut in voltage?
Cut-in voltage is the value of voltage at which appreciable current begins to flow when a pn junction is forward biased.
Zener diode with its forward biase?
acts like a normal diode in forward biased condition
