Spherical Capacitor: Explaining Inner Sphere Grounding
The outer sphere is connected to the positive terminal of a power source, while the inner sphere is connected to the negative terminal. Inner sphere grounding in a spherical capacitor refers to the process of connecting the inner sphere to a grounding point, usually a metal plate or rod, to dissipate any excess charge.

Solved A parallel plate capacitor is connected to a DC
A parallel plate capacitor is connected to a DC battery supplying a constant DC voltage Vo 700V and it has been connected for a long time. The left plate is at ground potential and the right plate is at positive potential. The separation between the capacitor plates is D- 7m and all the points in the picture are far from the edges of the plates.

Grounding the Positive Plate of an Isolated Parallel Plate Capacitor
Even when you ground the positive plate, it''s still near the negatively charged plate. Electrons that "want" to flow onto the positive plate and neutralize it are instead repelled by the nearby negative charge. Grounding only one of the capacitor plates does not make a circuit. Reply Chewy79

Grounding a 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).

they are not just 2 floating caps, they are two points with a imbalance of charge between them, one fully negative charged plate (from the first capacitor) and one fully positive charge plate (from the second capacitor), forget the fact both plates belong to different capacitors, they are still 2 points with a voltage present, if you set a path there will be a current until the

electromagnetism
On the negative plate, negative charge should be locally attracted to the positive plate, leaving behind positives, overall keeping the plate neutral. Practically, I''m pretty sure case 2 is wrong. What I think will happen is a miniscule amount of surface charge will be stored in the positive wire to maintain the electric field, but that charge will be way less than the stored

$begingroup$ Let''s say I have a charged plate capacitor. There''s a non-zero voltage across the plates. What if I connected only one plate to some object (possibly ground)? Can it change the voltage across the plates? I''m almost sure the answer is yes, it''s sufficient if the object we connect the plate to is of a different potential than the plate.

Does this mean that if I take a positive charge and place it a little distance above the positive plate the potential at that point where the charge is placed is higher than that of the positive plate inference the charge should go towards the positive plate when released and if able to move.This would imply that the charge wiuld move to the

What happens if a capacitor is connected to a ground?
In open circuit, no charge flows. If we connect both the capacitor plates it makes closed circuit, charge flows in the circuit, as a result charges on the plates neutralizes to zero. If only +ve plate of the capacitor is only connected to ground there is no closed circuit. no charges flows from the ground.
How to find the potential difference between C and D capacitor?
Now connect the wire joining C and D capacitor to ground and now record the potential difference at A, you will find it 7.5 and at positive plate of D it will be 0, and at negative plate of D it will be -2.5. This happens because negative charge from ground climbs on the positive plate of capacitor D and makes it neutral.
Does a positive plate of a charged capacitor cause 0V?
But such thing does not happen when we connect positive plate of a charged capacitor to the ground. AFAIK charge doesn't flow (to any significant extent in this context) unless you have a circuit. Connecting one end of a charged capacitor to anything has no significant effect. The explanation about a flow of charge causing D+ to be 0V is spurious.
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.
Why does a ground+plate system have an infinite capacitance?
This has contributed towards the accumulation of positive charge on the left plate.There was a temporary flow of current which stopped due to the potential on the left plate getting equal to zero.Since the positive plate is connected to the ground ,the ground+plate system has an infinite capacitance.
Can a capacitor get discharged if you connect a positive plate?
No. But if we connect positive plate to the negative plate then the capacitor will get discharged. Now consider a situation when we connect 4 capacitors A,B,C,D of equal capacitance in series and connect them to a 10 Volt battery. Now the P. D. between positive and negative plate of capacitor A will be (10- 7.5) i.e. 2.5 .
