What happens to charge stored in a capacitor when moving the plates?

AI Thread Summary
When moving the plates of a charged capacitor while keeping the distance constant, the charge stored in the capacitor remains unchanged if it is not connected to a voltage source. The capacitance will change due to the alteration in the overlapping area of the plates. Although the potential difference across the capacitor will vary, the net charge on the plates stays the same. The relationship U = QC applies, but the variables shift depending on whether the capacitor is connected to a voltage source or isolated. Thus, while the charge remains constant, the potential difference and capacitance are affected by the movement of the plates.

Let us take a charged capacitor and move the plates such that it the distance between them be constant. For example, one moves towards left and other moves upwards.
Assuming only overlapping area affects capacitance... WILL THE CHARGE STORED IN CAPACITOR CHANGE?
I know the capacitance changes.

Is the capacitor still connected to a voltage source or not connected to anything?

U = QC is valid in both cases, but in the first case U is constant and in the second case Q.
 
The capacitor is not connected to anything... hence the net charge in the capacitor plates should be same. But potential difference changes.

Thread 'Inducing EMF Through a Coil: Understanding Flux'

Thank you for reading my post. I can understand why a change in magnetic flux through a conducting surface would induce an emf, but how does this work when inducing an emf through a coil? How does the flux through the empty space between the wires have an effect on the electrons in the wire itself? In the image below is a coil with a magnetic field going through the space between the wires but not necessarily through the wires themselves. Thank you.

Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (Second part)'

I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8. I want to understand some issues more correctly. It's a little bit difficult to understand now. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. In the page 196, in the first paragraph, the author argues as follows ...
