Electric capacitance of plane capacitor
$$C = \frac{\varepsilon\cdot \varepsilon0\cdot S}{d}$$
C - electric capacitance
ε - dielectric constant (permittivity)
ε0 - permittivity constant
S - area
d - the distance between the plates
ε - dielectric constant (permittivity)
ε0 - permittivity constant
S - area
d - the distance between the plates
Find
It is known that:
