It's voltage that's being amplified by a voltage amplifier. Small changes in voltage at the input of the stage cause large changes of voltage at the output of the stage. That larger signal is then coupled out. The stage is said to have amplified the signal, amplified its voltage. And the stage's gain is a measure of how much. This is the simple answer. A further investigation into amplifiers and the underlying ideas in electronics will be needed to take this answer further.
What else can I help you with?
What is an amplification?
An amplification is an act of amplifying, expanding or making larger, or the act of increasing some quantity such as voltage, power or current.
What is the relationship between temperature and voltage amplification Theory and Mathematical Information?
With higher temperature, low voltage
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.
Which diode used for signal amplification zener or schottky or tunnel or none?
The diode that has a negative resistance region in its voltage-current curve.
How does a transistor make a signal bigger?
by injecting a small current into the base a larger proportional current will flow in the collector by adding a resistor into the path a big voltage drop will be evident therefore voltage amplification

The voltage of a given common source JFET amplifier is depend on what?
amplification factor
In electronic devices what are the factors that determine the voltage gain of an amplifier.?
The amplification factor Vout/Vin determines the voltage gain.
How current amplification is occur in a transistor?
A: Vacuum tubes are current amplifiers transistors are voltage amplifier. The voltage drop across the collector resistor causes amplification since very little current in the base will change a large current in the collector.
What does class D amplification mean?
Class-D amplification is where the amplifiers act as electronic switches.
Which of the transistor configuration is prefer?

Why Common Emitter Configuration is most commonly used in amplifier circuits?
the common emitter configuration is most widely used in amplifer circuits because of its high voltage,current & power gain.the common emitter configuration is most widely used in amplifer circuits because of its high voltage,current & power gain.
Why it is named as self Bias of BJT?
The Self Bias of the BJT is also called the voltage divider bias. It is called thus because it can stabilize the collector current, the base emitter voltage and the amplification factor.
