Detailed explanation of the role of the capacitor

Theoretically (that is, assuming the capacitor is a pure capacitor), the larger the capacitance, the smaller the impedance and the higher the frequency of passing. However, in fact, most of the capacitors exceeding 1 uF are electrolytic capacitors, which have a large inductance component, so the impedance will increase after the frequency is …
