SUMMARY

The discussion focuses on calculating the total impedance of a circuit involving resistors (R) and capacitors (C) in both series and parallel configurations. The user initially struggles to identify the arrangement of components and proposes an equation that combines the impedances of the components. It is confirmed that the pairs of components are in parallel and connected in series, and if the resistors and capacitors are equal, the total impedance can be simplified by doubling the impedance of one RC combination. Clarity in the question is emphasized for better assistance.

PREREQUISITES
  • Understanding of electrical circuit theory
  • Knowledge of impedance calculations in AC circuits
  • Familiarity with series and parallel circuit configurations

Homework Statement


[/B]
I need to find the total impedance for this circuit below. No values are given so I just need to write out an equation.

Homework Equations

The Attempt at a Solution



I'm having a hard time deciding what is in parallel/series. I took a guess and came up with:

( R * 1/jwc / R + 1/jwc ) + ( R * 1/jwc / R + 1/jwc )

So I assumed the top two components are in parallel, same with the bottom two.

Parentheses are free, so use all that are needed. This expression is incomplete; it might mean something to you, to everyone else we can only guess. Except for some notable exceptions, whitespace means nothing in mathematical expressions.

Yes, and those pairs are themselves connected in series.

If the R's are equal, likewise the C's, then you could find total Z by just doubling the impedance of one RC combo.

The question is not clear.
Do you speak about the INPUT impedance as seen by Vin or the OUTPUT impedance as seen by Vout?
(By the way: From your answer I can imagine what you mean - nevertheless, you should learn to ask clear questions).
