A parallel plate capacitor with a dielectric between its plates has a capacitance given by [latex]C=kappaepsilon_{0}frac{A}{d}[/latex], where κ is the dielectric constant of the material. The maximum electric field strength above which an insulating material begins to break down and conduct is called dielectric strength.

What happens when we put a conductor between the plates of a capacitor
When a conducting slab is inserted between the plates of a capacitor, it acts similarly to a conductor in that it disrupts the electric field between the capacitor plates. Conducting materials allow electrons to move easily, leading to the neutralization of any charge separation or voltage difference across the capacitor plates.

The equation C = Q / V C = Q / V makes sense: A parallel-plate capacitor (like the one shown in Figure 18.28) the size of a football field could hold a lot of charge without requiring too much work per unit charge to push the charge into the capacitor. Thus, Q would be large, and V would be small, so the capacitance C would be very large. Squeezing the same charge into a capacitor

6 FAQs about [Capacitors inserted into conductor plates]
Why do capacitors have a dielectric in the space between conductors?
Most capacitors have a dielectric (insulating solid or liquid material) in the space between the conductors. This has several advantages: Physical separation of the conductors. Prevention of dielectric breakdown. Enhancement of capacitance. The dielectric is polarized by the electric eld between the capacitor plates. tsl124
How does a capacitor charge a battery?
The capacitor is charged by connecting the two conducting plates to the two terminals of the battery. The charge of the capacitor is taken as Q, though it is the charge on one of the conductors, and the total charge of the capacitor will be zero. The electric field between the plates of the conductor is proportional to charge Q.
