Homework Statement Homework Equations The voltage across an inductor is V(T) = L i' Basic current division and voltage division . Step function where u(T) : when t is smaller than 0 : u(t) = 0 t >0 : u(t) = 1 The Attempt at a Solution The voltage source has...

Not helpful at all . Just had to say yes or no .

Hi , I have no problem to solve but just a bit of confusion on what determines the linearity of an ODE. Let's say the equation is (1 x^2) dy/dx + y = 0 Is it linear ? I would incline to say yes because the dependent variable and its derivatives are not in a product with each other but the...

First part: When the current sources are shut OFF , I find that Vo is 10V (correct). Second Part: (Shutting off 2A CS and 20V VS) This is the part that we were discussing. From what gneill told me , Since the current source is 1A and the resistor connected in parallel with it is 4 ohms , It is...

I just tried doing mesh analysis and Vo2 gives me 2V? The current in the lower right loop is (2/3)A.

With all due respect, studying is one way to learn but it doesn't hurt to simply explain instead of pointing me to go back to the books. I understand the concept and you saying to not do this problem is basically saying go fail your exam that's next week because you are not smart enough to read...

Current source is 1A .I don't know what to do in this case. To me , it looks like a source transformation but since the 4 ohms is not in series with the CS then , it is not possible. Edit: Nevermind , it does seem like the resistor is in parallel with the CS , then why is Thevenin's theorem...

I know what Thevenin's and Norton's theorem says but I don't really know it can be applied. For example , in this case , where is R_load and where are we short-circuiting to find Vth and Rth? From there , I know Thevenin's circuit can be built be a more precise question would be which elements...

No I do not. I tried to read my book and online tutorials but it does not make sense.. Especially in this case. Do you mind offering an explanation please?

Homework Statement [/B] Homework Equations There's not much to write here except parallel resistors equation. This is supposed to be a superposition problem. How did he use a source transformation because I have no idea why and where he did the equivalent resistor and why did a current...

Does this apply regardless of the direction of the current(s) ?

Hi , I'm currently stuck on a problem that requires to be solved with nodal analysis. I'm confused to what signs should I use when there's a voltage source in the loop. The problem: I already know the answer from the solutions but what I found is at V_0 : (V0 - 60V)/12 + V0/12 + (V0...

What do I do with the other part of the circuit? Does making R3 & R4 equivalent the same as taking the potential difference for one path only? (including the controlled source) Edit : How can it be ground when it connects both circuit together? Shouldn't a ground wire be attached to something...

Homework Statement Homework Equations V= iR Kirchoff's law for voltage The Attempt at a Solution On the left-most part of the circuit , I did use KVL (voltage law) and I ended up with Vs = i0 (R1+R2) which basically boils down to i0(2R) since R1 = R2 =R3 ... I'm not even...

Homework Statement Homework Equations Req =R1 + R2 Req = (R1*R2)/(R1 +R2) The Attempt at a Solution No idea how to do that . Was thinking maybe making the 3 and 2 ohms resistors equivalent (assuming parallel). I have no idea what to do with the top wire . How do I simplify...
