Is base emitter circuit and common base amplifier same?
No the base emitter circuit is not the same as a common base circuit. The three BJT circuits all have the base emitter circuit. Wheter each terminal is common to both inputs and outputs of the circuit determines the type of transistor configuration.Henry Lee Everson PE;229-560-9769
What is effect of an unbypassed resistor on the common emitter amplifier circuit?
An emitter resistor in a common emitter circuit will cause the stage to experience the effects of degenerative feedback if it is unbypassed. The degenerative feedback reduces gain. This is probably the primary effect in the described circuit.
How do you draw thevinin equivalent circuit of common emitter amplifier?

Why a capacitor is used for amplification in common emitter circuit?
A: The ratio of emitter/collector resistance is the gain. by adding a capacitor on the emitter the AC parameters will shift as a function of frequency
Capacitor from emitter to ground in common emitter circuit is called?
The capacitor is called a bypass capacitor , it provides a low impedence path for AC emitter current to groun.
What is the difference between a CB amplifier and CE and emitter-follower?
I think you mean a common emitter amplifier, which is an amplifier of voltage. Emitter-follower or common collector amplifiers are used to match impedances, or to amplify power or current. The emitter-follower is a type of common emitter circuit that has a resistor between the emitter and ground. The output signal is taken from the point between the emitter and its resistor.
Why use a npn transistor in a common emitter bjt single stage amplifier circuit?
You can use an npn or a pnp bjt in a common emitter amplifier circuit. The decision of which one to use is based on whether you want the collector and base to be more positive (npn) or more negative (pnp) than the emitter.
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.
Why bypass capacitor is used in common emitter ampifier circuit?
If a bypass capacitor is used the voltage drop across emitter resistance is reduced which in turn increases the gain.....
Why would there be a gain when you add the emitter capacitor to a circuit board?
A capacitor has lower resistance (impedance) as frequency increases. Adding an emitter capacitor effectively lowers the emitter resistance as frequency increases. Since gain in a typical common emitter amplifier is collector resitance divided by emitter resistance, this decrease in emitter resistance will increase gain as frequency increases.
What are the characteristics of a common emitter amplifier?
There are a number of characteristics found in a common emitter amplifier. Not only are the parameters considered, but also their performance. Characteristics and performance are: voltage gain/ medium; current gain/ medium; power gain/ high; input / output phase relationship/ 180 degrees; input resistance/ medium; and output resistance/ medium.
Why base in grounded in common emitter transistor as amplifier?
With a common emitter amplifier it's the emitter that is usually grounded.
