I mean, can I replace this configuration by one capacitor with one
resistor in series such that this resistor is equivalent to the other
two?
The answer is actually no.
For a single resistor and capacitor in series, the real part of the impedance is independent of frequency, i.e., the real part acts like a resistor.
$Z_s = R_s + \frac{1}{j \omega ...

For this particular circuit, the voltage across the R1/C1 branch #1 is fixed by V1, and that across R2 (branch #2) is also fixed, again by V1. That is, the fixed V1 decouples the two branches, so they can be solved separately (circuit #1 = voltage source V1 across branch #1, and circuit #2 = V1 across branch #2). Once these circuits are solved, the current ...

The basic idea is that all resistors can be modeled as a single material which has a resistance that is a function of its cross-sectional area $A$ only. (To be precise this is because all resistors have $0<R<\infty$, and for any resistor, $R$ is proportional to $L/A$ [this is the ONLY assumption needed for this derivation], so for fixed $L$ there ...
