A high-frequency signal will see the capacitor connected to ground, and travel through it, since it is a low impedance path, but a low frequency signal will not be affected by it. The capacitors to ground form a low-pass filter for the lines they''re connected to, as they remove high-frequency signals from the line by giving those signals a low ...
Start capacitors are typically wired in series with the motor''s start winding, helping to create the necessary phase shift and torque during startup. On the other hand, run capacitors are typically wired in parallel with the motor''s run winding, providing additional electrical power to keep the motor running smoothly and efficiently.
Y capacitors are used for common mode EMI filtering bypassing the interference from the wires to ground. Since safety capacitors are directly connected to the mains voltage, they can be subjected to voltage transients, power surges, overvoltage conditions, and other stresses resulting in device failure. They are designed for specific failure modes.
The voltage across the plates of a capacitor must also change in a continuous manner, so capacitors have the effect of "holding up" a voltage once they are charged to it, until that voltage can be discharged through a resistance. A very common use for capacitors is therefore stabilize rail voltages and decouple rails from ground.
This is not an issue with resistors, which obey Ohm''s law, but it is a limitation of capacitors. Therefore we can state a particularly important characteristic of capacitors: [text{The voltage across a capacitor cannot change instantaneously.} label{8.7} ] This observation will be key to understanding the operation of capacitors in DC circuits.

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.
Usually high value resistors are used in parallel with the capacitors to set the DC offset voltage. They can achieve a peak voltage rating higher than a single capacitor can (with a lower overall capacitance). Two polarized electrolytic capacitors wired in series with opposite polarities behaves like an unpolarized electrolytic capacitor.
Open capacitors usually occur as a result of overstress in an application. For instance, operation of DC rated capacitors at high AC current levels can cause a localized heating at the end terminations. The localized heating is caused by high 12R losses. (See Technical Bulletin #10). Continued operation of the capacitor can result in increased ...
When connecting a capacitor across L1 and L2, you must use a voltage-rated capacitor of at least 125% of the peak line voltage, which is 1.414 times RMS (root mean square) voltage. In other words, if you have a 120 VAC supply, you need at least a 150 VAC rated capacitor (1.25 x 120 V = 150 V).

This change in voltage is consistent and can be calculated exactly if you know the capacitance as well as any series resistance.
