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

#### Explanation:

**Series circuit:**

impedance=resistance+

Z=R+

Where,

R=resistance,

since resistance is related to type material,length of material,area of cross section of material,hence resistance is independent of frequency.

where,

f=frequency,

C=capacitance,

If we increase the frequency(f),

If
