Homework Statement DC analysis is required for the question in attachment. Vz=6V B=100 Vbe=0.7V Homework Equations The Attempt at a Solution I tried to find the result using the currents that were defined by the transistor. I found a result that was nonsense, the base current...

Hello, it is seen on the picture that its 1:2. :) And I didnt understand what you meant with transfer function :( You mean those stuff with complex variables (s)? Or is there a formula?

Hello people, I ve recently started to solve questions about magnetic coupled circuits, but I am stuck at a question that I ve seen for first time. I want to write the mesh equations but I simply don't know what should I do with the transformator in the middle when writing the equation for upper...

Homework Statement Find the expression of the current "i" by terms of time. The answer is 3e^(20t) Amps Homework Equations i(t)=I_final+(I_initial-I_final)*e^(-t/τ) The Attempt at a Solution I have found the initial current as 3 amps. However, after the switch had been changed for too long...

Nice! And can I simply discard the 5v battery and the 10 ohm resistor when I m doing the KVL walk?

Hmm, so I guess there's no current flowing through the line in the middle?

Hello dear Physics Forums community, I need your help! I m an electrical engineering student in second class, and I m stuck with a different kind of problem (probably different to me only, lawl) in the Circuit Analysis. I believe this problem will be a stepping stone for the other problems I...

Yeah, that makes quite sense, thanks! I failed to crush the mathematics again, lawl :)

Hello dear Physics Forums users! I ve recently passed to 2nd class, however I failed my Math II lesson, so I was solving some problems. Here is it, with my solution attempt: ∫(x+3)/\sqrt{}(x^2-4) ∫x/\sqrt{}(x^2-4) + 3/(\sqrt{}(x^2-4) Well eh, screw the integral on left anyway, what really...

I see...thanks for the answers guys :)

Hmm... I see. Will keep that in mind, thanks :) It would also be good to know some formal solution if there is one though :)

Hello dear Physics Forums users. I m currently studying some Integrals from a book which my elder brother studied with years ago, and one of the problems had the denominator: x^3-7x+6 Well, I m sure that's over my level, and teacher will never ask this, but in the solution it says its...

Oh cepheid, so you advice me to substitute the "t" with something like "kRC"? Edit: Did so, and found one of the answers on paper "1.6"

Hi tiny-tim :smile: Yeah, that's a weird question, but that's what exactly writes on the paper. Our teacher is a weird man anyways. But I guess, if sufficient data were given, we would use the equation "Vc=V*(1-e^(-t/RC)), right?

Hmm... I have translated the question from my test completely, and there isn't any other information given. So, does it mean that the question is incomplete?
