hi guys it’s been days i am searching and reading articles and books to find out what is the factor that a transistor amplify? which leg of transistor does provides this amplified factor?
i know what is bias
i know bjt and fet
i know pnp and npn
i know transistor can be used as switches
i know the bel guy and the other guy before him that created transistors
i know transistor controls current through input voltage signal applying on base
the only thing i can not understand is the factor that gets amplified and gets bigger in the transistor i don’t know which leg of transistor provides this? i did some test and saw led turns on with just bit of light through only my fingers with no power supply at all with a transistor and i assume its current that gets amplified thank you
