If C is the capacitance in Farads, ϵ permittivity of the dielectric, A is the area of plate overlap in square meters and d is the distance between plates in meters, then:

a)C = ϵd/A
b)C = A/ϵd
c)C = ϵA/d
d)C = d/ϵA

The correct equation is:

a) C = ϵA/d

The correct equation for the capacitance (C) in terms of permittivity (ϵ), area of plate overlap (A), and distance between plates (d) is:

a) C = ϵ * A / d
