Why do we use capacitors for power factor correction and not

A lot have mentioned that we use capacitors to correct power factor because loads are inductive, like motors. I''d like to expand a bit on the relationship between the two because your question shows good understanding of the basics but you''re missing a few key points which will make the whole thing come together.

Why 22pf capacitors for crystal oscillator?

I''m trying to understand why the Duemilanove reference design uses 22pf capacitors for the crystal oscillator circuit. As far as I know, the crystal is designed for a 20pf load capacitance. The equation for this is: Cl = ((C1 * C2) / (C1 + C2)) + Cs Where Cl is load capacitance, C1 and C2 are the capacitor values, and Cs is the stray capacitance of the …

8.2: Capacitors and Capacitance

Another popular type of capacitor is an electrolytic capacitor. It consists of an oxidized metal in a conducting paste. The main advantage of an electrolytic capacitor is its high capacitance relative to other common types of capacitors. For example, capacitance of one type of aluminum electrolytic capacitor can be as high as 1.0 F.

What Are DC-Blocking Capacitors And Why Are They Important

Generally, waveform systems can be broadly defined into power-related alternating current (AC) and communications-related radio frequency (RF) applications. Both employ waveforms to provide power or information. All of these devices require a blocking capacitor to ensure the waveform conforms to the desired specifications.

Power Line Carrier Communication (PLCC)

The coupling capacitor''s capacitance is of such a value that it offers low impedance to carrier frequency (1/ωC) but high impedance to power frequency (50 Hz). For example 2000pF capacitor offers 1.5MΩ to 50Hz but 150Ω to 500kHz. Thus coupling capacitor allows carrier frequency signal to enter the carrier equipment.
