because in ce configuration value of input voltage requried to make the transistor on is very less value of the output voltage or output current

Which terminal represents the control input of a bipolar transistor?
baseUmm....Device current results from forward biasing of the emitter-base junction.Thus you can:1. hold the emitter constant and apply control to the base (most common), or2. hold the base constant and apply control to the emitter (common/grounded base circuit, mostly used at high/very high frequencies).
What is the configuration of cascade amplifier?
In a cascade amplifier, two identical or non identical amplifiers are cascaded ,i.e., connected in series through a capacitor. They are mostly common emitter amplifiers that are cascaded together.The final gain of the cascaded amplifier is the product of the first amplifier's gain and the second amplifier's gain. However, the bandwidth of the cascaded version becomes lesser than the individual gains.
Why mostly in4007 as an power diode in bridge rectifier?
A: The reason is that a 1N4xxx diode is the most common and vastly manufactured and it is cheap and finally it can conduct 1 ampere which most circuit can use for operation. Actual in most cases it is an overkill but it is cheaper then anything else.
What is the function of ground wire?
A ground wire, in any context, can be used in two main ways. Mostly, it is used to collect stray signals from entering the circuit by grounding them out. In some cases, such as aircraft applications, it can also be used to make a common ground for all systems.
What powers Disneyland rides?
Magic, mostly.
Which transistor configuration is mostly used?
common emitter configuration is use for amplification purpose while common collector is use as buffer as its op is same as ip..

Which configuration is mostly used in transistor circuits?
A: I would say common emiter NPN , For no other reason then people think positive and logic was set aty positive 5 volts
Why mostly a transister is used as amplifier than diode?
A diode is not an amplifier. It is a rectifier with asymmetrical voltage breakdown voltages. Usually the forward voltage is around 0.6V to 0.7V (silicon), and the reverse voltage is smaller than breakdown voltage, which is much higher. A transistor can be used as an amplifier, by taking into account the fact that the voltage breakdown curves vary, usually collector-emitter, as a function of some other current, usually base-emitter, but this depends on the class of the amplifier and whether or not the transistor is driven into saturation.
Who is mostly used in the case of diode?
transistor//
What are common uses of a common emitter amplifier?
bcause amplification factor beta is usually ranges from 20-500 hence this configuration gives appericiable current gain as well as voltage gain at its output on the other hand in the Common Collector configuration has very high input resistance(~750 kilo ohm) & very low output resistance(~25 ohm) so the voltage gain is always less than one & its most important application is for impedance matching for drivingh from low impedance load to high impedance source

Why you bias in jfet transistor in nano ampere?
A: A FET has a very hi impedance it requires mostly potential as opposed to current like a transistor does,
How do you calculate the current gain of a transistor?
Bipolar transistor current gain is also called "Beta," or the h-parameter "hfe." beta = current_out / current_in The beta of a BJT is mostly determined by the thickness of the Base region, and by the excess doping in the Emitter relative to the Base. A thin Base and a heavily-doped Emitter leads to a high value for current gain. In a BJT, beta = Ic / Ib In a FET, beta is usually taken as infinity, since no current flows in or out of the gate. Beta is an impirical number. It means nothing unless the Ic is known or the load. It can have a beta from 1000 to 10 it all depends on the load.
How works heterojunction bipolar transistor?
The heterojunction bipolar transistor (HBT) is a type of bipolar junction transistor (BJT) which uses differing semiconductor materials for the emitter and base regions, creating a heterojunction. The HBT improves on the BJT in that it can handle signals of very high frequencies, up to several hundred GHz. It is commonly used in modern ultrafast circuits, mostly radio-frequency (RF) systems, and in applications requiring a high power efficiency, such as RF power amplifiers in cellular phones. The idea of employing a heterojunction is as old as the conventional BJT, dating back to a patent from 1951.
What was used for spying on the enemy?
small cameras mostly microphones attached to a emitter. which make radio waves that are picked up by a reserve.
Where are German shepherds mostly common?
German shepherds are mostly common in Germany since that is their origin.
