Thank you very much @gneill, my teacher posted the solution and it turns out the second calculations I assumed (with your help) were right! :D Do you know any good books with this type of exercices so I can practice for my exam? Thank you again for your time.

Yeah you're right, thanks. I'm now trying to calculate io(0+) and io(∞). For io(0+) I replaced the capacitor for a voltage source of 32V (assuming the other calculations were right) and applying KVL I figured that the intensity should be 32/6000= 5,3x10-3. But I'm not sure how the capacitor acts...

You're right about the io, I believe it should be 36-12=io(2000+3*2000+2*2000) io=2x10-3 A. For the Vc I just did 36-12, but now that I think of it maybe it's 32, as the voltage drops 4V in the first resistance. I struggle a lot to calculate voltages when the capacitor is in the middle of the...

Homework Statement It asks me to find io(t=0-), io(t=0+), and Vc(t=0-). C=100μF R= 2kΩ Homework Equations V=I*R, i(t)= i(∞)+[i(0+)-i(∞)]*e-t/τ, Vc(0-)=Vc(0+) The Attempt at a Solution [/B]I first tried to calculate Vc(0-) as it will be the same as Vc(0+), stating that at t=0- the...

Oh my god that was super silly.. Thanks gneill!

Thanks, do you think I got it?

Homework Statement Find the Thévenin's equivalent. Homework Equations V=IR The Attempt at a Solution [/B] I'm not sure if I need to take into account the internal resistance. And also, is finding thévenin's equivalent just calculating Rth and Vth? I'm really lost sorry. Many thanks.

Ahh thanks I was not sure if that was the right step, I think I can do the rest now. Thanks again.

Homework Statement [/B] I don't know how to simplify this circuit. Homework Equations [/B] V=IRThe Attempt at a Solution [/B] I thought of this, but I don't know if it's correct, could you help me please?

Yeah I'll add that thanks!

What do you mean by battery issues? Thanks.

Yeah I understood that but I was just pointing that he said orbital radius, and I've been told that when artificial satellites move around Earth their orbit is elliptical, so how would it be considering that it's not a perfect circumference?

The paper should be around 35 pages or so. But the think is that I can't understand most of the information i look for because I've never studied it and it's far beyond my knowledge. I'd like to go very deep into nanosatellites (ways to build one, projects in progress, steps to get one into...

Hi PF community! I'm currently doing a research paper on artificial satellites, and I've made a list of things that I'm going to explain in it, but I'm worried that it won't be enough. So, I was wondering if you guys could help me to add more topics to my list and how to approach more widely to...

Orbital radius? Aren't most of the orbits elliptical? Therefore it should be the semi major axis right?
