What will be the collector current of emitter base junction of a transister is reversed?

The question is poorly phrased and needs a grammatical cleanup.
If you mean to ask "what happens to the collector-emitter current of a transistor when the emitter-base junction is reverse biased" then the answer is that the transistor will turn off, and you will only see leakage current.

What is the difference between filament current and tube current?
The current supplied to the filament for heating is defined as the Filament current. whereas When the filament is heated to a high temperature, the electrons are emitted. The flow of electrons form Cathode to anode is the tube Current.
Changing alternating current to direct current is called?
Rectification
Formula of electric current?
The electric current is given by: I = V/R
What is called as Alternating current to Direct current converter?
A diode or rectifier converts AC to DC.
How does a constant current power supply works?
these are essential for circuits which are current sensitive, it regulates the amount of current which serves as protection for circuits. it is commonly used in Laser diode applications.
What is the difference between common base emitter transistor and common base transistor?
Common base transistor if the emitter is open current Ie=0 but a small collector current thus exist.this current is reversed biased collector to the base voltage it is represented by Icbo while common emitter is d base terminal is open circuit and the base junction is reversed biased current Icbo flow from the tcollector to the emitter in the external circuit this current is called leakage current.
Function of transister?
transister is the electronic divice used for correct current flow
What is unijunction tranjistor?
In unijunction transister there be a only one P-N Junction like diode, and current conduction takes place by either through holes or electrons.
Why is transistor called a current controlled device?
for a BJT to amplify we give input signalif suppose we use BJT in CE configuration input is given at Emitter-Base junction and output is taken at Collector base junctionthe input voltage increases or decreases the forward bias of the E-B junction affecting a change in the base current and we know that collector current is a function of base current collector current also variesso by selectively changing the base current we can effectively change the collector current
Why is collector current increased slowly with the increase of collector to emitter voltage of a common emitter?
The percentage of doping in emitter is higher than collector region.hence large current is flow to emitter than collector.
What bias conditions must be present for the normal operation of a transistor ampilifier?
Assuming you mean a bipolar junction transistor (BJT): 1. Reverse bias on the collector-base junction. 2. Forward bias on the base-emitter junction, that is 3. Sufficient to give the correct operating point of collector voltage/collector current.
How do you reset an immobilized 2011 Outback?
heart is defined as the best transister. Transister is best current for loop
What does it mean when you say a transistors junction is saturated?
It's called saturation because the collector voltage cannot go any lower. You've done all you can do with your base current (in Common Emitter configuration) to lower the collector voltage and support the collector current.
What is the effect of temperature on leakage current?
Flow of current in the collector circuit produces heat at the collector base junction. This increases the temperature. More minority carriers are generated in base collector region, since more bands are broken,the leakage current increases. In other word, leakage current increase when temperature increase.
Why do you have to connect a resistor to collector of transistor?
Type your answer here... to properly bias the junction for current flow thru the transistor. The voltage potential must be different on the base than the collector
What is Icbo in transistors?
Icbo (collector to base current when emitter is open) also called reverse saturation current as Is in reverse bias p-n junction diode.Regards
What is the alpha of the bipolar junction transistor?
The change of collector current with respect to emitter current. Typically 0.95 to 0.995. So a transistor with alpha of 0.95 might have an emitter current of 10 mA, collector current 9.5 mA. The "missing" current becomes base current and does not reach the collector. The more commonly used figure for current gain is beta, the ratio of collector current to base current, typically 50 to 500. In CB MODE It is called the common base, short-ckt, amplification factor.
