Low-frequency capacitor have large capacitance and are prone to leakage, while high-frequency electrolytic capacitor will not. 2. The internal resistance of low-frequency capacitor is larger than that of high-frequency electrolytic capacitor. 3. The capacity of high frequency capacitor is generally not as large as that of low frequency capacitor.
If the frequency is low enough (for a given capacitance and load values), then as the voltage follows its low frequency sinusoidal curve, the capacitor will have plenty of time to get charged/discharged and will follow this voltage closely. So there is basically not much voltage 'left' for the load - the capacitor is blocking it.
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.
@BigBear The presence of that capacitor causes the high frequency current to flow to ground. That current causes a large voltage drop in the resistor feeding it, the voltage of the high frequency signal on that capacitor node is therefore very low.
1. Frequency characteristics of capacitors The impedance Z of an ideal capacitor (Fig. 1) is shown by formula (1), where ω is the angular frequency and C is the electrostatic capacitance of the capacitor.
This is called the frequency characteristics of capacitor. Capacitor frequency characteristics refer to When a capacitor works in an AC circuit (especially in a high frequency circuit), its capacitance and other parameters will change with the change of frequency.
