We all understand that the impedance of a capacitor varies with the frequency of AC signals mathematically, through a formula. But once you understand it intuitively, you will be able to deduce complex circuits just by looking at them. This video explains the behaviour of capacitors with AC signals of varying frequency, why impedance decreases with increase in frequency and why it increases with a decrease in frequency.
