As frequency increases, does series and parallel RC impedance decrease?

Answer 1

Yes,series and parallel RC impedance decreases with increase in frequency.

Series circuit: impedance=resistance+#i#(reactance) Z=R+#iX_c# Where, R=resistance, #X_c#=capacitive reactance

#R=rho*l/a# since resistance is related to type material,length of material,area of cross section of material,hence resistance is independent of frequency.

#X_c=1/(2prodfC)#

where, f=frequency, C=capacitance, If we increase the frequency(f),#X_c# decreases. If #X_c# decreases,then Z also decreases.

As frequency increases, series RC impedance decreases, while parallel RC impedance increases.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
