7.Transistor as an amplifier | npn transistor



In this video we will learn transistor as an amplifier
How this transistor works as an amplifier..
To use transistor as an amplifier we use it in common emitter configuration and in active region . the small change(uA) in base current will result in high current(mA) in collector current . using this property of transistor we will use it as an amplifier.

    Agar beta badega too gm bhe badega ….to fir apne kaha ke gm multiply by Rl too voltage drop bhe jayda hogaa……..so why their is negative sign in that voltage gain??????

    If the flux capacitor is over biased will that alter the time warp factor?

    I passed b.sc in 2009 and I tried to understand transistor related topic from then many times from book and u tube ,but could not understand clearly …From your lecture now I have understood transistor related course clearly…..100%clear understanding….

    Sir CE amplifier has both voltage gain and current gain more than unity so why does it not work like an self generator?
