Solving Solid State Problem: Find ε'(ω) & ε''(ω)

Click For Summary

Discussion Overview

The discussion revolves around a homework problem involving the analysis of a parallel circuit consisting of two branches: one with a capacitor and the other with a capacitor in series with a resistor. Participants are tasked with demonstrating that this arrangement is equivalent to a capacitor with dielectric properties described by the Debye equation, specifically finding the real part ε'(ω) and the imaginary part ε''(ω).

Discussion Character

  • Homework-related
  • Mathematical reasoning

Main Points Raised

  • One participant requests assistance in solving the problem, indicating they have calculated the total impedance but are unable to extract ε'(ω) and ε''(ω).
  • Another participant asks for the initial work done by the first participant to better understand their approach.
  • A participant shares their expression for total impedance, Z(total), and mentions they have derived the real and imaginary parts of Z but have not yet found ε'(ω) and ε''(ω).
  • There is a request for the participant to provide the specific expressions for the real and imaginary parts of Z as well as the Debye relation.

Areas of Agreement / Disagreement

The discussion remains unresolved, with participants seeking clarification and further details from one another without reaching a consensus on the solution.

Contextual Notes

Participants have not yet provided complete expressions or assumptions regarding the Debye relation or the specific forms of ε'(ω) and ε''(ω), which may limit the analysis.

Homework Statement





please can anyone answer this question

consider the parallel arrangement of the following two circuit branches , one branch consists of a capacitor C1 , the other of a capacitor C2 series with resistance R . show that this circuit is equivalent to a capacitor with a dielectric satisfying Dybe equation ( ε'(ω) and ε''(ω)). Find them

i got total impedence but i can't extract ε'(ω) and ε''(ω)

please share ur ideas

Please first show us what you've got so far. (read the Guidelines)
 
i made Z(total)= 1/jωC2//(1/jωC2+R) then i got real part of Z +imaginary part of Z but it must be equivalent to a capacitor has real part and imaginary part

and up to this step i couldn't find ε'(ω) and ε''(ω)
 
Can you write down what you get for Re(Z) and Im(Z) as well as the Debye relation?
