# Magnitude of Impedience

See attached dwg. Can you please show me how to find the magnitude of Z (The impedience "looking in") as a function of frequency from 10Hz to 100KHZ? Note the inductor is 1mH the resistor 100 Ohms and the cap 1uF.

Please see the attached file.

Theory and Approach :

1 . Looking at the figure below, RC form a parallel circuit i.e. current flowing into the inductor is divided at the RC junction. This also implies that if you add up the total current flowing into R and C, you will get the current flowing in the inductor.

So we can conclude that ...
