Confusingly, I believe it''s the reciprocal 1/C that corresponds to the spring constant so a stiff spring is like a weak capacitor. For a given applied force (voltage), a stiff, high-k spring will displace very little (weak, low-C capacitor will store very little charge) and store 1/2kx 2 energy in the spring (Q 2 / 2C in the cap) . I also think of the resonant frequency as a mnemonic; spring

The grounding problem of electronic products is a common topic. This article only talks about a small part of it, mainly the grounding problem of the metal case and the circuit board.We often see that in some system designs, a high-voltage capacitor C1 (1~100nF/2KV) is usually connected in parallel with a large resistor R1 (1M) between the PCB board ground

You could measure the distortions & noise while trying to connect the mains ground to the case, but I would only ever attempt to do this via a capacitor. See if there''s an improvement. Even if you do see an improvement, things may go bad (THD&noise-wise) if you relocate the CD player to a different power outlet... even within the same household.

The chassis ground is a safe and effective path to divert that excess current. Ground is portrayed as a stable reference plane for electronics signals but realistically, it is anything but. All signals need a return path and the ground plane serves as one. A signal ground plane that becomes the return path of a digital signal is considerably noisy.

Learn MoreIt is true that in most cases one side of the capacitor will be grounded and the other attached to some rail, . There is no guarantee that grounding either pin of the capacitor to frame ground will discharge the capacitor. Further, by doing so you may actually be applying power to some circuit that does not expect it and can potentially damage it.
Grounded capacitor banks can interfere with a facilities ground fault protection system and cause the entire facility to lose power (main breaker trip). Harmonic currents in the ground path can cause harmonic interference with control and communication systems. Capacitor discharge currents may damage nearby surge arresters.
If a power factor correction capacitor is mounted on top of a wood pole at a height of 15 feet above ground (earth), the metal capacitor case is required to be grounded. If a submersible pump in a metal well casing is protected at 30 amperes, the equipment grounding conductor connected to the motor and the well casing must not be smaller than ? .
What you might be seeing is that in a specific circuit, one terminal of the capacitor is already connected to ground (or any other bus / voltage reference), meaning that if you then connect the other terminal to the same bus you've created a circuit to discharge the capacitor.
When a capacitor is being charged, negative charge is removed from one side of the capacitor and placed onto the other, leaving one side with a negative charge (-q) and the other side with a positive charge (+q). The net charge of the capacitor as a whole remains equal to zero.
Furthermore, if you accidentally connect the ground terminal of the capacitor to the metal case, the capacitor will not discharge. Because of this, it is a good idea to discharge all capacitors by connecting the terminals together (either with a conductive material or a resistor) until the capacitor is discharged. (You can check with a multimeter.)
