i have doubts about the figure showing only holes an electrons in the following page:
http://www.allaboutcircuits.com/vol_3/chpt_2/8.html
the arrow in blue shows the electron(s) flowing out of the base.i am not really sure if base current happens that way.what i had heard was that the holes of base(of npn bjt) that are lost in recombination are regenerated by the breaking of a covalent bond in the p material.a hole and an electron are generated.this electron(s) flows out from the base wire and the hole stays in the base...please comment
