Why Your Capacitor Bank Should be Left Ungrounded

Figure 1 is used to illustrate how a grounded capacitor bank can interfere with the ground fault protection system of a resistive grounded system. The main concern arises when a capacitor fails as shown in Figure 1 by the "X". Since medium voltage capacitors fail shorted, a faulted capacitor is like applying a line to ground fault on the facilities

Do Guitars Need Capacitors? Here''s What You Should Know

This is especially true if the guitar is equipped with single-coil pickups, as single-coil pickups tend to produce a weaker signal than humbucking pickups. A capacitor can help to boost the signal strength of the pickups, resulting in improved sustain and a fuller sound. Overall, whether or not a guitar needs a capacitor depends on personal preference and the type of sound the player is
