I am currently having issues solving this problem as I have not been asked to solve for something like this before. Any help would be much appreciated. Image is attached.

 

Hi.
Can you calculate impedance in Laplace domain?
Do you know what impedance poles are?

 

I understand how Laplace works from differential equations. But I am not very good at applying it to circuit analysis.

 

Here is the table showing the impedance in Laplace domain.
It is about the middle of the page:

Now, can you calculate impedance of that circuit, Z(s), in Laplace domain?

 

So by the structure of the capacitance Z(s), I would choose B. Is my logic correct in that?

No, your answer is not correct. Please post your Z(s) and your calculation.
Here is the circuit represented in Laplace domain.

 

My apologies for resurrecting such an old thread but Ive been working on this exact same problem in an FE practice exam. I can find the answer in the back of the book easy enough, but what I'm curious about is what the poles actually represent? I've attached the calculation and the answer puts poles at s=0; s= -1/(R2C2) but what does that actually mean? How do I take the equation I've come up with and use it to find those pole locations? Thanks in advance for any guidance.

 

So I've "cheated" to try and understand what is going on with this problem and maybe answered my own question. When I plug those correct answer values in, the functions get a 0 in the denominator so it essentially goes to infinity. So really what the question is asking is, what values of (s) will make this function go to infinity. Somehow I missed that that is was is meant by "find the poles".
