No 0.7 is Vbe which while voltage between the B and E nodes but we need to only Potential at B and we know that E is at ground and the Voltage drop iis due to the 4.7K resistance.
Amazing Video you made me understand what i never understood even tough i have a bachelor degree in electronics applied in avaiation thank you from france
good video sir . but i think you mistakenly used the wrong value of Vb. From Vbe=Vb-Ve where we assume Vbe is 0.7v and with known Ve is 0. Vb should be 0.7V
Hfe for noise small signal gain and how it amplifies, how to count the the limitations on Hfe small signal gain max. What is Noise Figure and what it is used for? Hertz calculation on inductance difference are in the form of ampere right? So without a bc547, just inductor, resistors and 5 volt source as standard could count be replicated as circuit. What would the circuit look like? The amplifier part was the tricky circuit diagram replica from the transistor only using resistors, capacitors, inductors and no transistors or circuit switches but pure maths on V=IR Kirchhoff's nodes.
No , it is fixed. But there is process variation in manufacturing so it has some tolerance. Lets say BC547 VBE(on) varies from 580mV to 720mV. Hope I answered your question.
Hey...sorry for inconvenience caused to you. As I already told in video, I am not much handy in sniping tool so it was taking to write something. It is hard to write using mouse.
![[Solved]- Numerical for a BJT (Ib, Ic, Vce & Vcb =? )](http://i.ytimg.com/vi/gu_FYvL5zc4/mqdefault.jpg)
When you calculated Vcb why did you use 5V instead of subtracting voltage drop across the resistor
5v is not VB it is base biasing voltage, VBB... VCB = 6.8 - 0.7 = 6.1v
No 0.7 is Vbe which while voltage between the B and E nodes but we need to only Potential at B and we know that E is at ground and the Voltage drop iis due to the 4.7K resistance.
@@Music-qg3ihSo Vc is not 6.8 but Ic•Rc??
The clicking sound is so annoying but overall the lecture is superb
Thanks for your feedback...I already removed clicking sound in new video.

Glad to hear that. You can many more such videos in this youtube channel.

Hey...thanks for pointing it out.

Thanks for the super clear explanation, really helpful, keep up the good work
Thanks for your compliment.
God bless you, this is the best video i have seen on electronics
Glad it helped

What happens during saturation? What is the lowest voltage Vce will go down to?
Hello...Please check the Vce(sat) of the selected bjt in datasheet . you will get vce(sat) value there.
Sir , how Vce is -ve while calculation by KVL????
Is the value of VBE= 0.7V a constant value or can be changed
No , it is fixed. But there is process variation in manufacturing so it has some tolerance. Lets say BC547 VBE(on) varies from 580mV to 720mV. Hope I answered your question.
How can we measure node voltages and branch currents in ltspice for the same question?
Hey...I think you need to watch basic ltspice video.
Could u do the pnp version?
Noted your comment, sure i will make video for PNP. Thanks
It was really helpful 🙏
Glad it helped you.
thank you very much
@@theoryandapplication7197 Thank you.
Add one emitter resistor then do the same calculation
Thanks for Your feedback.
Last you take vb=5v i think it must be.7v
Hey...why it must have 7V ?
@@ElectronicsCircuitHubECH he is saying 0.7 volt. Vcb =Vce-Vbe as simple. You applied there Vbb
Your Ic value is wrong it should be 45.7mA

You take 10 times more that should be needed,what waste of time
