Find the capacitance of parallel plate capacitor with dielectric between its plates.
Answers
Answer:
A capacitor is a device used to store charge.
The amount of charge Q a capacitor can store depends on two major factors—the voltage applied and the capacitor’s physical characteristics, such as its size.
The capacitance C is the amount of charge stored per volt, or
C
=
Q
V
.
The capacitance of a parallel plate capacitor is
C
=
ϵ
0
A
d
, when the plates are separated by air or free space. \displaystyle {\epsilon }_{\text{0}}ϵ
0
is called the permittivity of free space.
A parallel plate capacitor with a dielectric between its plates has a capacitance given by
C
=
κ
ϵ
0
A
d
, 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.
