How to Discharge a Capacitor (with Pictures)
A discharging circuit with high energy efficiency is designed for supercapacitors. In this design, the capacitors are connected in parallel during charging and connected in series during discharging. With this method, the voltage of the capacitors in series becomes two times larger during discharging; thus, the step-down circuit can be …
Any technician with minimum electrical knowledge can determine or calculate reactive power compensation. The most common practice is using "a single" electricity bill. The emphasis here is on the "single" electricity bill as it is precisely here that a series of errors can start, which can often end up, with higher costs than those involved when a capacitor bank is …

Only one capacitor providing sufficient capacitance is needed for luminaires with several lamps. Parallel compensation does not affect current flow through a discharge lamp. The requirements
Placing capacitors in parallel increases overall plate area, and thus increases capacitance, as indicated by Equation ref{8.4}. Therefore capacitors in parallel add in value, behaving like resistors in series. In contrast, when capacitors are placed in series, it is as if the plate distance has increased, thus decreasing capacitance.
