Thanks sir.. It's very helpful for me..

[@shantanupatil7488]

Sir, please please make a video on different types of amplifier. It will be very helpful.

[@ArponPaul]

Does this course cover the topic frequency response of amplifiers?

[@altuber99_athlete]

Okay, so we shortcircuit capacitors because their capacitance is considerably big. However, really thats just an approximation; can we analyze the circuit without necessarily shortcircuiting the caps.? Aaand, what happens if the capacitance isn't big enough? I suppose then we can't treat the caps. as shorts. Thanks in advance! Great playlist 👍

[@nehareddy4619]

Sir please increase ur voice,it is not audible,but ur explanation is super sir

[@juturubharathi8510]

Why we use capicitors in this ?what is its role?

[@ayushverma1755]

What was the need to add both resister and capacitor at the emitter if we just wanted the maximum current gain? We could have simply put a straight wire. (8:03)

[@gnanupraneeth9376]

With Re resistor we will get stable DC biasing voltage(check voltage divider biasing circuit) for stable operation of transistor.. With Ce capacitor we will bypass the AC signal .. If we don't bypass the AC signal , the AC signal will lose some voltage (voltage drop) in Re resistor before reaching output.. Therefore voltage at output reduces.. Gain reduces.. So Re is important for biasing.. Ce capacitor for bypass the AC signal to the output.. Both are playing vital role

[@kaustabhdas1592]

@@gnanupraneeth9376 sir in the later part the resistor Re is open circuited right? So that ac signal can flow through the capacitor with minimal resistance?

[@himanshulal510]

Sir what would have happened if emitter resistance wasn't by-passed.

[@sushmitasaha6909]

sir please post power amplifiers oscillators videos

[@sail_sail30]

where are lectures of POWER AMPS??

[@sabcam2000]

And what about the DC analysis?

[@BATSARK007]

why we don't short the emitter and ground via wire?

[@damodardarshankolla767]

what you are explaining is wonderful but it would be much more better if there were no ads disturbing the flow....thankyou :)

You said that dc have no frequency means 0 frequency What will happen if we are driving this amplifier with pulsating dc I mean if we don't use filtering capacitor at the o/p of rectifier Reply please

Can anybody pls give me link of dc analysis of transistor

[@putdalimeindecoconut]

capacitors have values in order of micro. so how can you they have large values ...large enough to make xc=0?

[@kharanshiluveru7934]

Your point is completely right! However you are missing one basic which is also not told by him. The value of capacitance is generally choose depending on the frequency. If you are operating a 100MHz(which is generally frequency of most electronic circuits) then even 1microFarad capacitance make Xc=0.
