... Some general rules to keep in mind: a) Our transistor amp amplifies small signals, typically mV. b) Typical DC collector current is a few mA. c) The gain (Vout/Vin) of a CE amp is ≈ RC/rBE if RE = 0. rBE is intrinsic to the transistor. You can't touch it! It is given by: rBE = hie/hfe ≈ 25 mV/IC. So ...

History of the transistor
A transistor is a semiconductor device with at least three terminals for connection to an electric circuit. The vacuum-tube triode, also called a (thermionic) valve, was the transistor's precursor, introduced in 1907.
