when no input in applied PD is zero but when ac input is given it will be positive for all values of Vm, even if -Vm^2 term is there because the first term in the equation is (Vcc.Vm) and Vcc is greater than Vm. power dissipation will be maximum when Vm =2Vcc/π and then it will reduce but it will remain positive.I hope it is clear now.
When we use complementary symmetry circuit then we have one PNP and one NPN transistors but when we have transformers in push pull circuit we have same type of transistor.
Nice video mam and nice explanation
Thanks!!
loved your teaching mam thank you
It's my pleasure
At 7:04, how will power dissipation increase if there is a -Vm^2 term Shouldn't the power dissipation decrease?

@@conceptech2018 yeah it's clear now. Thank you!
Thanks a lot for better information 🙏🙏🙏🙏🙏
Most welcome...keep watching
Do you provide the PDF of your lecture sheet ?
Maam, can i get the ppt of this lecture?
Madam explain power rating clearly
Nice but in the class B amplifier one PNP and One NPN are used
