A current amplifier this a device which heightens the current of the input signal at its output. If we are speaking of semiconductor devices i.e. transistors, than this form of amplification is done so by applying input signal the the base of the transistor, and drawing the output singal from the emitter. This amplifier can also me called an emitter follower. A current amplifier will only yield a gain of less than 1, but the current can be amplified up to 10x the input current.

What is current series feedback amplifier and its uses?
current series feedback amplifier=series parallel feedback amplifier or voltage to current amplifier,or TRANS CONDUCTANCE AMPLIFIER.
What is a common application of a cc amplifier?
current amplifier
What is one common application of a cc amplifier?
current amplifier
Why does a CE amplifier have a high gain?
GAIN is a function of load current but basically a small current in the base will make a big change of collector current therefore making a transistor a voltage amplifier as opposed to a current amplifier
How does power amplifier differ from a conventional voltage amplifier?
A voltage amplifier does not have to supply significant current bur a power amplifier does.
Input impedance of current shunt feedback amplifier?
The input impedance of a current shunt feedback amplifier is the open loop impedance of the amplifier divided by 1+(A*beta)
What are the advantages and disadvantages in using common collector amplifier?
Current gain. At the cost of no voltage gain.
How does a transistor function as an amplifier?
A: The small base current will control the collector current flow by adding a resistor this changes of current flow will be evident as a voltage amplifier.
Is transistor a current amplifier or voltage amplifier?
depends on the circuit it is used in:CE/CS is inverting voltage amplifierCC/CD is noninverting current amplifierCB/CG is noninverting voltage amplifier
Types of Negative feedback amplifier?
voltage amplifier feedback current amplifier feedback transconductance feedback transresistance feedback
Is power amplifier is basically a current amplifier?
idiophones membronophones Aerophones chordophones electrophones
What electronic circuit use a small current to control a large current?
