Does the dielectric constant affect the capacitance of a capacitor?

AI Thread Summary
The dielectric constant (K) of a medium significantly affects the capacitance of a capacitor, particularly in parallel plate configurations. As the dielectric constant increases, the electric field between the plates is reduced, requiring more charge to achieve the same voltage. This relationship indicates that the presence of a dielectric effectively increases the capacitance by allowing for greater charge storage. Dielectrics are materials that can be polarized, which enhances their ability to influence capacitance. Overall, higher dielectric constants lead to increased capacitance in capacitors.

Why do the capacitance increase with increase in dielectric constant(K) of the medium between the capacitor?
 
Physics news on Phys.org
You can look at it in several ways. One is to look at the electric field between the plates (I assume parallel plates). Since there is a dielectric between the plates, the electric field gets reduced and you will need more charge on the plates to increase the voltage between them. Using the definition of capacitance you can figure it out from there.

Dielectrics are materials that are readily polarized. That is, the + and - can be separated a little bit. Sticking a dielectric inside is like sticking another capacitor between your existing widely spaced capacitor.

Thread 'How to picture the vector potential?'

Susskind (in The Theoretical Minimum, volume 1, pages 203-205) writes the Lagrangian for the magnetic field as ##L=\frac m 2(\dot x^2+\dot y^2 + \dot z^2)+ \frac e c (\dot x A_x +\dot y A_y +\dot z A_z)## and then calculates ##\dot p_x =ma_x + \frac e c \frac d {dt} A_x=ma_x + \frac e c(\frac {\partial A_x} {\partial x}\dot x + \frac {\partial A_x} {\partial y}\dot y + \frac {\partial A_x} {\partial z}\dot z)##. I have problems with the last step. I might have written ##\frac {dA_x} {dt}...

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 ...
