sir q1 acts for positive cycle of signal and gives result of 180 degree phase shift on output ,then why here graph is upward or positive for q1 shouldn't it should be negative or downward so that q1 and q2 makes complete signal after combinig at output?
These are output obtained by Q1 and Q2, not across the Load resistance.. These Output will work as input for T2 transformer and then we get our final output current in opposite phase of input across the Load resistance. (talked in previous lecture)
Q1 & Q2 both are NPN transistors. But due to centre tapping transformer phase of input waveforms differ by 180 degree so Q1 works for positive cycle n Q2 works for negative. Thank you
Sir , University exam me help hoga ye playlist se??? Sirf aapke videos dekhlu to chalenga University exam me ?? Subject name - Analog and digital electronics
Sir please can you tell me that how to you put value Idc=Icmax/π please sir explain it....that is a formula to convert AC current into DC current or not....please sir explain it sir...🙏🙏
Dear Shivam, For half wave sinosuidal signal, DC current = max current/pie. For full wave sinosuidal signal DC current = 2 × max current/ pie. This formula is explained in half wave and full wave rectifier videos in analog Electronics lecture series. Thank you and best wishes Beta.
sir aap ye efficiency class b power amplifier ke liye bata rahe ho , but usme aap push pull class b bata rahe ho. is the efficiency same for class b and push pull class b ?? or else there is a different efficiency for class b power amplifier. ?? or the efficiency is same for all the class b amplifier , push pull , and complementary symmetry ??
Thank you very much sir for this series. We are learning now . 🤗
God bless you Beta and wish you success 🙌
Thank You Sir🙏 It is helping us in M.sc Physics🙏
God bless you all.
Thanks sir Now I can Go Fearlessly for My 4th sem examination 🗿🗿🤝
Sir you Are very Helpful Here
Thank you very much sir for your teaching
You are welcome Beta 😊
Sir ye derivation Class B Push pull Amp. Ka hai na
Yes Beta.
nice explanation
🙏🙏
Really helpful thank you sir ☺️
Thank you Baisali Beta 😊

Dear Student,
Consider magnitude of transistor collector current and get the efficiency value. Thank you.
These are output obtained by Q1 and Q2, not across the Load resistance.. These Output will work as input for T2 transformer and then we get our final output current in opposite phase of input across the Load resistance. (talked in previous lecture)
Thank you so much sir
You are welcome Beta 😊
Q1 and Q2 both are positive ? is it correct ?
it seems like rectifier output waveform not like amplifier.
Q1 & Q2 both are NPN transistors. But due to centre tapping transformer phase of input waveforms differ by 180 degree so Q1 works for positive cycle n Q2 works for negative. Thank you
love you from pakistan
God bless you Dear Ahmed..
Sending you Love n best wishes from India ❤🤝

Sir ,
University exam me help hoga ye playlist se???
Sirf aapke videos dekhlu to chalenga University exam me ??

Check your syllabus content and
Watch Analog Electronics & STLD Playlist for your exam. Surely you can rely on my content Beta.

Dear Shubham,
Any amplifier that works in class B mode will have same efficiency. Please share this free education to your friends. Thank you 😊
Sir isme humne ac signal diya h toh input m power dc kaise h
Dear Monika,
DC power is taken from biasing energy like Vcc and Ic. From external DC source.
Thank you 😊
Thank you very much sir
