Including value of ro makes the final equations complicated and in most situation ro effect can be ignored. So ro is considered infinity

sir when u applied kvl to base emitter loop u took Vbe=0.7 but we r doing ac analysis y we r taking that junction voltage also.In previous Re models u just took dynamic resistance n u have not taken this junction voltage but here u r taking y?

0:18 How is this circuit is common emitter ? here we have the base as input and emitter as output and collector is connected to ground so this circuit must be common collector .

collector gets grounded in ac equivalent so it is common collector

@akbarbadshah92488 жыл бұрын
Hai sir, in CE amplifier emitter is grounded because it act's both input and output port.similarly in CB amlifier base is grounded.But CC amplifier as shown in above video no collector terminal is grounded,then how it act's as CC amplifier.

sir,please reply.and the next dout is current always prefers low resistive path.if there is no resistance in collector terminal then all the current from Vcc will flow through collector terminal only,it will not enter the base resistance.

Both are coupling capacitor C1=> will block the input DC voltage which coming from the source C2 =>Will block the DC voltage which coming from the amplifire circute

common emitter, look at what side is connected to ground (common ground) so since emitter is connected to ground this is a common emitter
