I am having a problem regarding calculating the impedance of the two circuits below:
Everywhere I search I always get a description of what to do if they are connected in series or in parallell, however no one I have found so far explains how to use both parallell and series to make an Impedance function using the jw method. Would be extremly happy if someone explains the best method of getting the jw impedance function and also what does R1 // L1 stand for in these cases. Why is R1 // L1 often refered to as (R1 * L1) / (R1 + L1) and not (1/R1 + 1/L1) Like regular parallell functions.
The values on the different parts in the schematics are just examples, I would like to know how to make the formula using the signs like R1, C1 and so on.
Thanks in advance
