Engineering Circuit analysis, determing impendance.

AI Thread Summary
The discussion revolves around calculating the impedance of a circuit using the formula for equivalent impedance. The user initially struggles with their calculations, leading to an incorrect answer despite consistent results with test values. After further examination, they realize that their Laplace transformation was incorrect, which was the source of the problem. Once corrected, they successfully find the right answer and express gratitude for the assistance received. The conversation highlights the importance of verifying each step in circuit analysis.

Homework Statement



I need to find the impedance of the following circuit:

Homework Equations



\frac{1}{Z_eq}=\frac{1}{Z_1}+\frac{1}{Z_2}
Z=R
Z=\frac{1}{i \omega C}

The Attempt at a Solution



This should be really simple, but I seem to have some troubles. So: \frac{1}{R}+i \omega C=\frac{1+i \omega CR}{R} and then Z_eq=\frac{R}{1+i \omega CR}. But the answer seems to be wrong.

That's the answer I got when I calculated it. I tried it with test values it was consistent. Why do you think it's wrong?

As I said this should be really simple, I just get the wrong answer for the calculation, that this impedance is part of. Maybe it helps if I post the whole problem?

Edit: I found out my Laplace tranformation for the circuit was wrong. I got the right answer now. Thank you.

Sorry I couldn't help more. Glad you figured it out :biggrin:
 
You did plenty enough. I was sure the problem was there, but your confirmation made go trough every step. Thank for the help!
