What is Current amplification factor in common emitter configuration?
comparerission between CB,CC&CE
Why does ce configuration provide large current amplification while the cb configuration does not?
The common emitter (CE) configuration provides large current amplification because it utilizes a small base current to control a much larger collector current, resulting in a significant current gain (β). In contrast, the common base (CB) configuration does not offer the same level of amplification since it is designed for high-frequency applications and has a lower input impedance, which leads to a smaller output current relative to the input. Additionally, the CB configuration does not allow for the same degree of control over the collector current by the base current as the CE configuration does.
Why cb and cc configuration are not preferred as an electronic switch?
Common emitter is the preferred circuit because the collector voltage drops to a well defined low value when the transistor is 'on', therefore it absorbs only a small amount of power.
Why CE mode amplifier is preferred over CB and CC?
CE gives high gain and amplification as compared to CB and CC. That's why its preferred. input and output resistance moderate value,so many stages coupled to each other without using any additional impedence matching circuit.so maximum power transfer takes place from one stage to another. THAT'S why it is preffered.
What are the applications of CB configuration?
the CB configutration is having low impedance & hence used in I-V converters(current -voltage converters)
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..
Is Common emitter configuration has high input impedance or medium input impedance?
Slightly less than cc configuration but greater than cb
Which configuration gives no current gain?
cc/ce/cb doesn't give the no current gain
Which transistor configuration has the highest voltage gain?
Common Emitter(CE) Configuration possess largest voltage gain among the three(CE CB CC).
What is the common transistor configuration used for signal amplifier?
Class A amplifiers for signals and class AB for power output. The bias is often set up as a self biased amp.
Why common emitter configuration is preferred?
Reason: The common Emitter mode has voltage and current gain better than the other two configurations(CB and CC). i.e it has a current gain greater than that of CC mode and greater voltage gain than that of CB mode.
Which of the transistor configuration is prefer?
It depends on what you want to do with the transistor. Class A, common emitter, is used for voltage amplification. Class C, common collector, is used for current amplification. There are other classes and configurations but, again, it depends on what you want to do.
