Capacitance of a parallel plate capacitor is ________(a) C = ^A∈⁄d(b) C = ^∈⁄d(c) C = ^A⁄d(d) C = AThe question was posed to me during a job interview.The query is from Capacitive Transducer topic in portion Transducers of Electrical Measurements

Answer»

The correct choice is (a) C = ^A∈⁄d

The BEST explanation: The capacitance of a parallel PLATE capacitor is given by the relation,

C = ^A∈⁄d

where,

A is the AREA of CROSS section of the plates

d is the distance of separation between the plates

∈ is the permittivity of space.
