electromagnetism
You are essentially correct. The "floating" wire you have drawn will act as a stray capacitance to ground. Because the shape is a poor shape for a capacitor the capacitance will be very small. So the circuit will look like two capacitors in series, connected to ground, one capacitor being much larger than the other.
Why does a capacitor plate connected to Earth lose
When you connect the right plate to Earth from far away the system looks like an uncharged object as its potential is 0. Hence the charges on the outer surface of both plates is 0. Now the charge on the inner plate of the

Is the charge on the plates of a parallel plate capacitor induced
So, yes, if you started charging one plate of a parallel plate capacitor with a static electricity generator with the opposite plate connected to ground, then the opposite plate would try to draw in electrons from the ground or expel electrons into the ground in order for the capacitor as a whole to remain electrically neutral and thereby minimize the electrostatic energy of the system.

Grounding to a big capacitor : r/Teslacoil
Unclear why you think a capacitor would be on the ground connection. The point of a power ground is to supply or sink a large volume of charge.

Should capacitors be grounded?
So, attaching one capacitor plate to ground simply fixes the electric potential of that plate; if the ungrounded plate has charge Q, the grounded plate will have charge − Q. how could the grounded plate gain -Q charge. The ideal ground supplies the − Q charge to the plate without changing potential.
Earthing the plates (one or both) of a parallel plate
Intermediate condition - Plate A is neutral, but Plate B has charge 60 x 10^-6 C, so it induces -60 x 10^-6 C charge on inner side(2) of plate A and 60 x 10^-6 C charge on outer side(1) of plate A. Now, charge on outer
Marine HF SSB Installation and Grounding

Avoid 1/4 Wave Lengths •Use a DC Block as pictured in example. The helps prevent galvanic currents as we only need to pass RF. Capacitors are .15µf
When one plate of the charged capacitor is earthed the charge
This causes the charge on that plate to neutralize because the earth can either supply or absorb an infinite amount of charge. The charge will flow from the plate to the ground until the potential of that plate becomes equal to the earth''s potential (zero). This process affects the overall charge distribution in the capacitor.

Four-plate capacitive power transfer system with different grounding
Normally, four metal plates are required to form electric field coupling and provide a current flow path in a CPT system [3]. Two plates are used as primary power transmitters, and the other two are used as secondary power receivers, resulting in at least two mutual-coupled capacitors among the four plates.

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.
Generally why are one of the two plates of a capacitor earthed
The concept of earthing or grounding a capacitor''s plate involves connecting it to a point that is at a reference potential, typically the earth potential. This practice ensures that the capacitor operates reliably and consistently by providing a stable reference for voltage levels and minimizing electrical noise. Grounding helps maintain the

However, small capacitors used this way will slightly roll off the very highest frequencies by swamping them to ground and through a tiny amount of feedback. but it could be sttrapped across the plate resistor, or run to ground as well. It does add a bit of feedback, but the amount is almost negligible tonewise. SY. Ex-Moderator. Joined

6 FAQs about [Capacitor plate grounding]
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 is the 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.
How do you ground a capacitor?
Straightforwardly interface the ground side of the capacitor to the ground plane instead of directing it as anything but a trace. Use the Star Grounding Technique for Analog Circuits: Star grounding utilizes a solitary point on the PCB as the main ground point. This point, and just this point, can be viewed as a ground potential.
Can a capacitor bank be grounded?
This question often arises, and the answer is usually no for the following reasons: • Grounded capacitor banks can interfere with a facilities ground fault protection system and cause the entire facility to lose power (main breaker trip).
Does a grounded plate mean there is no charge on a conductor?
No, the fact that one plate is grounded does not mean that there is no charge on that plate. Look up "charging by induction" which leaves a charge on a conductor even though it is grounded. What is your definition of capacitance if the two plates do not carry same amount of opposite charges?
Does grounding a capacitor cause a discharge?
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.
