How does a transistor amplify in a common emitter configuration?
The base is excited by a very low current. That turns the transistor on so that a higher amount of current flow comes out.
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.
What is cb configuration of the transistor?
A sexy transistor are two type. NPN and PNP..... c means common b means base .
What configuration was the first successful prototype transistor at Bell Labs connected in?
Common base connection.
Which configuration of bipolar junction transistor which will give both current gain and voltage gain?
high voltage gain :- common base since the ratio of output impedance to the input impermanence is very high in common base mode high current gain :-common collector since it is the ratio of Ie/Ib
What if base current is zero in a transistor used as an amplifier with common emitter configuration?
output current is zero
How does a transistor amplify in a common emitter configuration?
The base is excited by a very low current. That turns the transistor on so that a higher amount of current flow comes out.
Why common emitter configuration is mostly used for transistor as switch?
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
What is common collector bipolar junction?
A circuit in which the input signal is applied to its base and the collector is earthed (grounded) is known as common collector configuration of BJT (BiPolar Junction Transistor)
Which transistor configuration has the highest input impedance?
Common Emitter Configuration has maximum impedance.
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.
What is an explanation of different transistor configurations?
there are 3 types of configuratons......they are 1.common emmiter configuration 2.common collector configuration 3.common base configuration
How a transistor transfers resistance?
The input current of transistor is approximately equal to output current .Suppose in common base configuration the emmiter current is approximately equal to collector current if neglect the very small value of bae current.Even though the input resistance is not equal to output resistance,the currents are same ,so we can reliase that the transistor transfers resistance to get same currents at both ends.
What is cb configuration of the transistor?
A sexy transistor are two type. NPN and PNP..... c means common b means base .
What configuration commonly employed in bipolar transistor amplifier?
Common Emitter - Class A Amplifier.
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..
What configuration was the first successful prototype transistor at Bell Labs connected in?
Common base connection.
