A Transistor can be biassed in two ways Forward bias and Reverse bias A transistor is said to be forward bias if the positive of the transistor is connected to the positive terminal of the battery and negative to the negative terminal of the battery.A Transistor in the converse condition is known as reverse biassed

∙ 14y agoConnect a current source ( internal resistance very high ) to the diode in such polarity as the diode conduct in forward direction. Connect a voltage meter across the diode (so that it reads positive if connects a analouge meter). The reading you are getting is the forward voltage. In normal diodes available in the market will have a forwrd voltage of the range 0.5v to 0.9v

How much forward diode voltage is there with the ideal diode approximation?
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
What is the diode 1n34 forward voltage?
Roughly, 200m mV.
Are diode forward and zener voltages the same?
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
How much voltage is there across a germanium diode when it is forward biased?
About 0.2V
What is a substitute for a germanium diode?
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).
What is the forward breakdown voltage for in4007 diode?
there is no forward breakdown voltage for any diode
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.
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.
What will happen if current is more than required in diode?
If the applied voltage is greater than maximum forward voltage, the diode will get damaged..
What happend when a diode is forward biased?
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.
What do you mean by DC forward voltage?
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.
How much forward diode voltage is there with the ideal diode approximation?
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
Is forward voltage drop of schottky diode more than tunnel diode?
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.
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 the diode 1n34 forward voltage?
Roughly, 200m mV.
Are diode forward and zener voltages the same?
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
What is the voltage drop in diode IN4007?
forward drop is the same as any other silicon diode, about 0.7V
