actually it is slightly less than 1, due to base-emitter forward bias voltage.

What is voltage gain?
Voltage gain is the ratio of the output voltage of an amplifier to its input voltage.
What is effect of load on voltage gain of common emitter amplifier?
it makes sound :) trollolololol
Why does amplifier gain reduce?
Since we know that the amplifier gain is given by A=Output voltage/input voltage (where A is the amplifier gain) So, it can be written as output voltage=A*input voltage, so when the output part increases gain increases but when input part increases gain decreases
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.
What is the effect of Rs and RL on the voltage gain of an amplifier?
it reduces the gain
What are the advantages and disadvantages in using common collector amplifier?
Current gain. At the cost of no voltage gain.
Main use of a Common collector transistor amplifier is?
No voltage gain
The voltage gran of an amplifier is 200 The decibel voltage gain is?
The voltage gain of an amplifier is 200. The decibel voltage gain is? Answer Gain in dB = 20 * log 200 = 46 dB

What are the disadvantages of using common emitter amplifier?
Disadvantages of CE amplifier:1. It has a high output resistance.2. It responds poorly to high frequencies.3. It has high thermal instabilities.4. It's voltage gain is very unstable.
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.
Common collector amplifier does not have voltage gain but still provide power gain?
It still has a current gain significantly high though the voltage gain is close to unity.
What is use of voltage amplifier?
obtaining voltage gain of a weak signal
What is the effect of Rs and RL on the voltage gain of an amplifier?
it reduces the gain
How does a voltage controlled amplifier work?
A Voltage Controlled Amplifier or VCA is a device whose gain is set by the voltage level of a control signal.
