The current you set it to work at. Using for example resistors you can set the voltages and currents at a certain DC level. At that point the transistor will work. It is mostly (but not always) used to put the transistor in its linear region.

What is use of diode?
Diode is a two terminal semicon. Diode is a Switching device
When operating as a voltage regulator the breakdown in a Zener diode occurs due to which effect?
avalanche
Why the n-jfet is operated with the negative voltage not the positive voltage?
In a JFET the only insulation between the gate and the channel is a reverse biased diode junction, if this junction becomes forward biased then the gate and channel are effectively shorted and the device no longer acts as a transistor (it will act as a forward biased diode instead). In the n-channel JFET, the gate is the P-side of this diode and the channel is the N-side of this diode. To keep this diode reverse biased (and the device operating as a transistor) therefor the gate MUST always be maintained at a voltage more negative than the most negative section of the channel.
What is a large slower acting diode?
it is a rectify diode
What is the difference between a 1N4007 diode and a 1N4007S diode what does the s do?
The difference in the 1N4007 diode and the 1N4007S diode is the voltage. The 1N4007S has a higher voltage but the meaning of the S is not listed.
What is use of diode?
Diode is a two terminal semicon. Diode is a Switching device
What is the incremental resistance obtained from the diode equation?
The incremental resistance of a diode is the inverse of the slope of the V-I curve at the operating point.
How do you determine the operating parameters of a diode over its full operating range?
Look at the "Diode Markings"
What DC operating point means?
"The application of a DC voltage in forward bias mode to a circuit containing a diode will result in a specific DC voltage and DC current across the diode, known as the DC operating point, Q point (VDQ, IDQ)." source: http://www.doe.carleton.ca/~achar/notes_2507/Lab3_tutorial_diodes.pdf
What is meant by the threshold point of a diode?
it means the entrance point of a diode
What is more referred to use si diode or a ge diode?
silicon diode is preferred more when compared with germanium diode because in silicon diode the operating voltage is 0.7v where as in germanium diode the operating voltage is 0.3v , germanium is temperature sensitive so it can be easily destroyed by increasing temperature hence silicon diode is preferred more
What is the definition of silicon diode?
A silicon diode is a tiny electronic component having two terminals, usually a switch or limiting device.
When operating as a voltage regulator the breakdown in a Zener diode occurs due to which effect?
avalanche
What is the definition of resource utilization in operating system?
a
What is zener break down voltage?
The point in the forward operating region of the characteristic curve where conduction starts to increase rapidly is called Knee voltage of a PN Junction Diode.The breakdown voltage of a diode is the minimum reverse voltage to make the diode conduct in reverse.(or) Breakdown voltage is a parameter of a diode that defines the largest reverse voltage that can be applied without causing an exponential increase in the current in the diode.-- Dinakar
What is OA in OA79 diode?
In OA79, the letter A stands for rectifier diode and O stands for Germanium. It acts as a point contact germanium diode and also be replaced with 1N4148 depending on the circuit.
Why can't a conventional pn junction be used for high frequency switching applications?
If the reverse recovery time of the diode is too long for the operating frequency, the diode will never turn off.
