Voltage amplifiers are genrally used to amplify voltage signals to a certain db and amplification is a linear process. In power amplifiers it is not required to amplify voltage it is not significant and genraly equal to input voltage. It is significantly used to produce a large current at the output.

What is the basic difference between transistor as an amplifier and a step up transformer?
The output power of an amplifier is greater than its input power, whereas the output power of a transformer is almost the same as its input power. In other words, an amplifier increases acts to increase power, whereas a transformer only increases voltage.
What is the difference between differential amplifier and summing amplifier?

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.
Difference between instrumentation and operational amplifiers?
An instrumentation amplifier is made out of 2 or 3 operational amplifiers.
What is phase difference between input and output waveforms of ce amplifier?
180 degree phase shift

What is the difference between optical amplifier and repeater?
Difference between Amplifier and Repeater 1. Amplifier is used to magnify a signal, whereas repeater is used to receive and retransmit a signal with a power gain. 2. Repeater has an amplifier as a part of it. 3. Sometimes, amplifiers introduce some noise to the signal, whereas repeaters contain noise eliminating parts.
What is the difference between an amplifier and a booster?
an amplifier is electronic equipment that increases strength of a signal and a booster is voltage regulation in (DC) direct current electrical power circuits. Basically an amplifier increases strength and a booster regulates voltage.
What is the difference between normal amplifier and magnetic amplifier?
normal amplifier is a mathametical operation analog the computer, magnetic amplifier is sound operation of the signal
What are the Difference Between AF Amplifier and RF Amplifier?
The amp for audio freq. is a AF amplifier. The RF amp is for radio freqs.
Can I use a preamp into a speaker?
You need a power amplifier in between.
What is the difference between an amplifier and a speaker?
The subwoofer is the actual speaker making the loud bass. The amplifier is what powers the subwoofer and makes it work how it does. It only uses the low frequencies from the audio source and amplifies it.

Whats the main difference between small signal amplifier and large signal amplifier?
1.Small signal amplifier can be designed easily using s parameter while large signal amplifier not.
What are the difference between Erbrium doped fiber amplifier and semi-conductor amplifier?
A doped fiber amplifier amplifies light in the fiber as a LASER.A semiconductor amplifier is an electronic circuit that amplifies electrical signals.
Can a power amplifier amplifies the power?
Question: Can a power amplifier amplify the power? An amplifier can amplify the voltage or the current. Power can be converted to heat.
