http://www.allaboutcircuits.com/vol_3/chpt_2/8.htmlIn this website The explanation on Bjt is very good . But i have some doubts in it. It is mentioned in the site that 1) holes in the base may diffuse into the emitter and combine with electrons, contributing to base terminal current. I understand the diffusion process but what is that base terminal current. 2) Also if the holes have been diffused into the emitter wont the emitter acquire negative charge and start blocking the incoming electrons from emitter? 3) http://www.tpub.com/content/neets/14...s/14179_69.htm If we increase Vce do the minority carriers i.e holes in collector flow to the base therby making the base more positve and increasing current flow?
