Question

What is a current amplifier?

Answer 1

1. A current amplifier is an electric device that is used to increase the magnitude of an input signal's current by a preset signal.
2. This process is known as the current amplification of an input signal.
3. The equation of the current amplifier , the current gian of the current amplifier can be written as :$A_I=\frac{outputcurrent}{inputcurrent}$,where $A_i$is the current gain.
4. A continuous signal or a time-varying waveform can be used as the input.
5. The current amplifier should, in theory, keep the voltage component of the input signal unaltered during this process of current amplification.
6. An current amplifier is used to provide higher current gain
7. Amplifier is used to detect the changes in base current as the change in base current can cause a high deviation in the collector current.
