Capacitance of a Grounded Capacitor
Suppose one plate of the capacitor is grounded which means there is charge present at only one plate. We know that the potential across the capacitor will be 0, i.e., V=0. And capacitance of the Capacitor will be C=Q/V. C=Q/0 implying C=∞. So it means that the capacitance of a grounded capacitor is Infinite.

The polarized capacitor looks a little different and includes an arced line on the lower part of it, along with a positive terminal on top. This positive terminal is super
Grounding a capacitor
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?
Negative terminal of capacitor to ground
kak111''s schematic shows an instance in which the negative side of the capacitors are grounded in one case, the positive side in the other. They are serving as filter capacitors for a bipolar power supply. One instance (of many) in which neither side of the capacitor would be grounded would be the speaker output of an audio amplifier.
How to distinguish the polarity of capacitors | Leadsintec
The basic principle is that when the anode of an electrolytic capacitor is connected to the positive terminal of a power source (with the black lead of the multimeter for resistance measurement) and the cathode to the negative terminal (with the red lead), the current passing through the capacitor will be small (i.e., the leakage resistance will be high).
capacitor ground or not?
The voltage on the positive terminals of polarized caps must always be greater than the negative terminal. What voltage the negative terminal is at is not significant.
How Capacitors Work
A 1-farad capacitor can store one coulomb (coo-lomb) of charge at 1 volt. A coulomb is 6.25e18 (6.25 * 10^18, or 6.25 billion billion) electrons. One amp represents a rate of electron flow of 1 coulomb of electrons per second, so a 1
Question about capacitor and ground :

What happens if we ground both sides of a capacitor?
The electric potential of an ideal ground does not change no matter how much charged is added or removed. So, attaching one capacitor plate to ground simply fixes the electric potential of that plate; if the ungrounded plate has charge QQ, the grounded plate will have charge −Q−Q.

6 FAQs about [Where is the positive ground of the capacitor]
What happens when a capacitor is grounded?
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.
What happens when positive and negative charges coalesce on capacitor plates?
When positive and negative charges coalesce on the capacitor plates, the capacitor becomes charged. A capacitor can retain its electric field -- hold its charge -- because the positive and negative charges on each of the plates attract each other but never reach each other.
What happens when a capacitor is charged?
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.
How does a positive armature hold up a capacitor?
Physically when electrons try to flow out from the negative electrode to the ground, the positive armature holds them up. (1) For a capacitor to discharge, it is necessary though not sufficient for there to be a means for charge to move from one plate to the other.
How do you know if a capacitor is positive or negative?
The positive lead is often longer than the negative lead. Additionally, the positive lead may be thicker or have a different shape compared to the negative lead. Inspecting the lead length and shape can provide clues about the capacitor’s polarity.
What is a negative terminal capacitor?
The negative terminal (-) of the capacitor is connected to the ground (GND) or negative voltage reference. The schematic provides clear guidance on how to correctly orient the capacitor within the circuit to ensure proper functionality and prevent polarity-related issues.
