    Oh. well thanks, I feel like an idiot now :D

    Effective resistance for Thevenin's theorem

    Homework Statement Me again. I again got confused with 2 similar things done differently on two different places. Let's say we have some arbitrary circuit and we want to replace a part of it with thevenin's generator. We also need to calculate effective Thevenin's resistance, which is where i...

    Voltage generators in open edges and Thevenin's generator

    Oh well this then becomes a very simple problem. Thanks so much.

    Voltage generators in open edges and Thevenin's generator

    Okay, i can find potentials at nodes 1 and 2 in the first case easily. But what do i do in the second case? How do I treat capacitor when using node potential method for example? My idea is that that branch doesn't contribute to overall current entering the node 0 or 1 , so it can be omitted in...

    Voltage generators in open edges and Thevenin's generator

    Well first i find the Thevenin's EMF ( in function of Ig). Then i close the switch and now the voltage of the edge with R3 is equal to the voltage of the capacitor when the switch is open + Δq*C. There is no current flow trough the capacitor so we are left with a simple circuit with elements ...

    Voltage generators in open edges and Thevenin's generator

    No, it does not. I'm allowed to solve it any way i want, but i mentioned Thevenin's theorem since i have confusions related to it and i tried using it. Any solution is welcome ;)

    Voltage generators in open edges and Thevenin's generator

    Homework Statement I hope you can see the picture clearly. Someone drew lines over it,so please try to ignore that. The problem here is to determine the current of ideal current source Ig, if following parameters are known: -E1=50V, E3=30V -R1=200Ω, R2=500Ω, R3=3kΩ, R4= 10 kΩ -C=0.7 μF...

    Engineering Calculating net change of capacitor charge in a circuit

    I solved the task. First i considered the case with the closed switch First edge ( all orientation is from the left) can be replaced with an ideal current generator with current I= I1. Now, edge one and two (which form a Norton generator) can be converted into a Thevenin generator with ems Et...

    Yes, that is correct.

    Engineering Calculating net change of capacitor charge in a circuit

    I updated the question. E3 is known, not E1. I apologize.

    Engineering Calculating net change of capacitor charge in a circuit

    Homework Statement This problem apparently has a simple solution if you are good with circuit theorems but no matter what i try or how i combine them, it's just impossible. Given a circuit on the picture, and circuit parameters E3=12V,R1=1kΩ,R2=30Ω,R3=150Ω,R6=200Ω, if it is known that current...
