hellow guys,
i was watching a video lectures about using the bipolar transistor as an amplifier
the instructor said that it is possible to use it as a voltage,current or power amplifier but he did not clear this sentence
can anyone illustrate the difference with some circuits ?
i also need some tutorials so i can begin designing amplifiers...
thank you

 

hi Alimash,
There are tutorials on our site.

Also check the 'common emitter' and 'common collector' links on the right of that page.
