safety
The only GUARANTEED safe answer is to discharge the capacitor, through a suitable resistor, across the capacitor terminals.. It is true that in most cases one side of the capacitor will be grounded and the other attached to some rail, HOWEVER this is NOT TRUE in all designs. There is no guarantee that grounding either pin of the capacitor to frame ground …
Shunt Capacitors and Reactors, Series Capacitors
2. With series capacitors the reduction in line current is small; hence if thermal considerations limit the current, little advantage is obtained and shunt compensation should be used. 3.

A Fundamental Rule of Grounding (EE Tip #124)
In my mind, it is grounding. The fundamental rule for grounding is depicted in Figure 1. By "ground" I mean the common 0 V potential to which signals are referenced. The "chassis ground", if grounding conductors had 0 Ω impedance, would also be 0 V—but, unfortunately, it never is. Yet there are still systems that are sufficiently ...

The total capacitance of N capacitors in series is the inverse of the sum of all inverse capacitances. If you only have two capacitors in series, you can use the "product-over-sum" method to calculate the total capacitance: Taking that equation even further, if you have two equal-valued capacitors in series, the total capacitance is half of their value. For example two …

Capacitors in Parallel. Figure 19.20(a) shows a parallel connection of three capacitors with a voltage applied.Here the total capacitance is easier to find than in the series case. To find the equivalent total capacitance C p C p, we first note that the voltage across each capacitor is V V, the same as that of the source, since they are connected directly to it through a conductor.
What is the difference between Coupling, Decoupling, and Bypass ...
While decoupling capacitors are connected in parallel to the signal path, coupling capacitors are connected in series to the signal path. In this way, a coupling capacitor filters DC signals instead of AC signals. Coupling capacitors are widely used in amplifier circuits. For example, in single supply op-amp based amplifiers, where the non-inverting input is biased …
