Most noticeably, capacitors reduce losses, free up capacity, and reduce voltage drop. Let’s go a little bit into details. By canceling the reactive power to motors and other loads with low power factor, capacitors decrease the line current. Reduced current frees up capacity; the same circuit can serve more load.
By canceling the reactive power to motors and other loads with low power factor, capacitors decrease the line current. Reduced current frees up capacity; the same circuit can serve more load. Reduced current also significantly lowers the I 2 R line losses. Capacitors provide a voltage boost, which cancels part of the drop caused by system loads.
Low-voltage capacitors can either reduce the kVA requirements on nearby lines and transformers or allow a larger kilowatt load without requiring higher-rated lines or transformers. High-voltage capacitors for primary high-voltage lines have all-film dielectrics and are available with 2.4- to 25-kV ratings over the range of 50 to 400 kvar.
Two kinds of capacitors perform power factor correction: secondary (low voltage) and primary (high voltage). These capacitors are rated in kilovars. Low-voltage capacitors with metallized polypropylene dielectrics are available with voltage ratings from 240 to 600 V over the range of 2.5 to 100 kvar, three-phase.
Capacitors provide power just when reactive loads need it. Just when a motor with low power factor needs power from the system, the capacitor is there to provide it. Then in the next half cycle, the motor releases its excess energy, and the capacitor is there to absorb it. Capacitors and reactive loads exchange this reactive power back and forth.

Even low-voltage capacitors can deliver a jolt if not discharged properly. Component Damage : If you''re working on a circuit and inadvertently touch an uncharged capacitor, the sudden discharge of stored energy can damage sensitive electronic components, such as transistors, integrated circuits, or other capacitors.
Switched-capacitor stages are described which can function with very low (typically 1 V) supply voltages, without using voltage boosting or switched op-amps. Simulations indicate that high per- formance may be achieved using these circuits in filter or data con- verter applications. 2. INTRODUCTION.

The other interesting part of this plot is what happens at 200 milliseconds when the source goes back to zero. Note that the node 3 voltage immediately jumps to a negative value.
