6 FAQs about [Capacitors to separate high and low frequencies]
Can a capacitor be a low pass high pass filter?
Capacitors can be low pass high pass filters because their impedance changes with the frequency of the input signal. If we create a voltage divider of 1 stable impedance element (resistor) and 1 variable impedance element (capacitor) we can filter out low frequency or high frequency input signals.
Why does a high frequency pass through a capacitor?
Why does a high frquency pass through a capacitor and a low frequency doesen't? A capacitor is essentially two conductors separated by a dielectric (INSULATOR). Therefore, current does not pass through a capacitor but a result equivalent to it passing through can be obtained if the current is alternating [AC] (as opposed to direct [DC].)
Why does the voltage drop across a capacitor decrease when frequency is low?
The impedance ZC Z C increases as we decrease frequency, so the voltage drop across the capacitor decreases when frequency is low. Doesn't that mean that the capacitor is letting through all the low frequency signals... Why is the lower picture showing us that all the high frequency signals are going through the capacitor?

Do ceramic capacitors filter better at higher frequencies?
If the capacitors were ideal, there would be no way that smaller value capacitors could filter better at higher frequencies. But every ceramic cap maintains a capacitor-like behavior up to some frequency. Then the parasitic inductance starts to assert itself and ultimately, at high frequencies, dominate the impedance characteristic.
What is a capacitance-frequency relationship?
The capacitance-frequency relationship has many applications: AC Line Filters: Large capacitances are used to pass low-frequency signals and block high frequencies. Tuned Circuits: Capacitors and inductors can create resonant RLC circuits to filter specific frequencies.
