Why the circuits that are common emitter configurations called "common emitter"?

Question

please, associate with ur answer any useful references

Answer 1

The Emitter junction of the transistor is the common point btween the Collector, or output, and the Base, or input of the circuit. The Emitter, in these circuits is the common ground point of the circuit, so both the input and output are "common" to the Emitter.

Answer 2

Because the emitter is the common connection between input and output in this configuration.
i.e. The input signal is applied to the base and emitter, the output signal is taken from the collector and the emitter.
(This statement ignores all the coupling and bias components but is effectively what happens).

The other configuration used is common base, where the input is connected to the base-emitter and the output taken from the base/collector.

Answer 3

Because the input is at the base, and the output is at the collector. Both the input and the output use the emitter, so the emitter is common to them, hence the name Common Emitter.

Answer 4

'elementary experience', I even have discovered, is elementary yet frequently would not make experience. 'Posh human beings' are no longer any further and no much less concern to this undertaking than the different team of persons. as an occasion, it became into elementary experience interior the C16th and C17th centuries for persons to have faith that the earth became into flat and that the earth became into the centre of the universe. human beings additionally, in each social team, believed that gadgets while dropped fall at diverse speeds, in accordance to their weight! Galileo, along with his telescope, observed that planets moved around the sunlight - and suffered for it while imprisoned via the Catholic Church of the time. He additionally confirmed, via dropping diverse gadgets from the Leaning Tower of Pisa, that one and all gadgets fall on the comparable fee in a given gravity field. (forget the 'parachute result' for gentle gadgets.) pass on. try it. Drop a e book and a pen on the comparable time, inspite of the load transformations, and spot what occurs. positioned a small piece of paper onto a e book and drop them. See which falls quicker! some 'posh human beings', i.e. college pupils, have been requested what timber have been produced from. maximum suggested 'timber' yet no longer one in all them suggested carbon-dioxide. So why are we so troubled approximately burning down forests and worldwide warming? My granny used to assert that it became into elementary experience to place a dock leaf onto a nettle sting, and it could make it extra desirable. She wasn't 'posh' and the 'previous spouse's tale' did no longer artwork. nevertheless do it nevertheless! i attempted the 'gravity test' together with her and while she observed what got here approximately, she suggested, "that's what your coaching is doing then?" i did no longer advise disrespect yet i ought to work out that she became right into slightly questioned. My elders continuously wished me to 'get an coaching', possibly for bragging to associates, yet when I did, they did no longer like it plenty. They continuously suggested, "we decide on you to do extra desirable than we did." Then got here, "i think you think of you're too solid for us now." They weren't posh yet how plenty elementary experience does this make? If 'posh human beings' have not got any elementary experience, then, whoever they're, they're in elementary with something human beings, as we are able to all have faith all sorts of rubbish! It is predicated upon existence journey and coaching, somewhat than 'waiting made' reasons exceeded down by way of the years.
