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, …
When one of the plates of an isolated capacitor is grounded, does the charge become zero on that plate or just the charge on the outer surface become zero? The charge on that plate becomes the same as the charge on Earth.
Grounding either pin of a capacitor to frame ground does not necessarily cause a discharge. In fact, it may apply power to some circuit that does not expect it, potentially damaging it.
Grounding requires a conducting pathway between the ground and the object to be grounded. Electrons will travel along that pathway. Lesson 2 of this unit of The Physics Classroom has been focused on methods of charging and discharging objects. One principle that continually arose was the relationship between force and distance.
Thus, the grounding of a positively charged electroscope involves the transfer of electrons from the ground into the electroscope. This process works because excess positive charge on the electroscope attracts electrons from the ground (in this case, a person).
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.
Like contact charging discussed earlier, grounding is simply another example of charge sharing between two objects. The extent to which an object is willing to share excess charge is proportional to its size. So an effective ground is simply an object with significant enough size to share the overwhelming majority of excess charge.

Get PriceIn 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 ...
