A parallel-plate capacitor with plate area A and separation d contains a dielectric with permittivity ε. What is the capacitance of this system?
A
ε
A
d
\frac{εA}{d}
d

A
, where the permittivity directly determines the capacity to store charge per unit voltage in the electric field.
B

d
\frac{ε_0A}{εd}

A
, where the free space permittivity is modified by the dielectric material properties to reduce the effective storage.
C
ε
d
A
\frac{εd}{A}
A
ε
d
, representing the proportional relationship between dielectric properties and geometric factors of the parallel plate configuration.
D
A

\frac{A}{εd}
ε
d
A
, where the area contributes positively while both permittivity and separation provide resistance to charge storage capability.
