Why in common collector amplifier however you change value of resistance not amplifier in voltage?
The question does not quite make sense. It sounds like you are asking why does changing the emitter resistor in a class C common collector amplifier not affect the output voltage? If so, the answer is that the common collector is an emitter follower, meaning that the emitter will follow the base, less the base-emitter junction voltage, within the limits of hFe. The resistor is simply there to ensure output biasing when the base voltage goes low.
What is the formula for VE in a common collector amplifier?
what is common collector
What is the other name for the common-collector amplifier?
emitter follwer
what is the Primary function of the common collector amplifier?
current gain
Why output voltage in common base amplifier is in phase to input voltage?
The output of a common emitter stage is inverted, it is not out of phase.
Application of a common - collector amplifier circuit?
Common collector amplifier can be used as a voltage buffer and in impedance matching
Main use of a Common collector transistor amplifier is?
No voltage gain
Which bjt transistor amplifier can be used as a voltage buffer?
the common collector can use as voltage buffer
What are the advantages and disadvantages in using common collector amplifier?
Current gain. At the cost of no voltage gain.
Why is common emitter is greater than common collector?
Common-emitter gives more voltage gain because a common-collector amplifier has a voltage gain of 1. But a common-collector can have a power gain because the input impedance is much more than the output impedance.

Why we kept VOLTAGE collector to emitter half of voltage vcc?
We bias the common emitter amplifier to have a collector-emitter voltage of one half of Vcc in order to set the operating point halfway between the two extremes.
How transistor produce 180 degree phase shift?
In the common emitter configuration, a class A amplifier, an increase in base voltage (the input) leads to an increase in base-emitter current which leads to a proportionately larger increase in base collector current. That pulls the collector towards the emitter, which decreases the collector voltage. Since the collector is the output, this configuration is an inverting amplifier.
Why there is 180 degrees phase shift in common emitter amplifier?
In the common emitter amplifier, an increase of base-emitter current causes a larger increase of collector emitter current. This means that, as the base voltage increases, the collector voltage decreases. This is a 180 degree phase shift.

Can you use CC configuration as an amplifier?
The Common Collector configuration amplifies current, by having the emitter voltage follow the base voltage, with an offset of the forward conduction voltage of about 0.7 volts, with a current gain of beta. (hFe)
