Transistor AMPLifier HelP !
could some1 explain it entire circuit in terms of electron movement i.e how the voltage drops in each component in terms of electron flow
1)i can't understand the voltage divider bias i find it extremely difficult
please explain it interms of electron movement in anyone of the circuit diagrams mentioned below (explain the voltage drops for the electron current
2)also to be frank i can't understand what basically Vbe and Vce is
is it the barrier voltage between base emitter and base collector respectively
if so then how can voltage drop occur at CB junction
it experiences no impedance and only attraction then how can the voltage drop there
what is meant by emitter base juction has less resistance and collector base junction has high resistance.But actually electrons from emitter get attracted to the collector easily how come that region has high resistance
i have posted the circuit diagram
i have many doubts there about how the voltage drop between R1 and R2 gives forward bias to the base emitter
also which current's voltage is getting dropped there
in my diagram its showing collector current
but collector current itself arises from the emitter
also u have not biased the emitter till now then how did u get Ic
forward bias provided by the voltage drop of Ic
see u have not biased it and u r about to bias the emitter only from voltage drop of Ic
then where did u get that Ic from
Ic comes only after biasing EB
so could some1 explain the entire circuit qualitatively in terms of electron current starting from the ground please don't explain in terms of conventional current. I want only electron flow
i want to know how can the voltage drop cause forward bias to the base emitter
