1.	Which is the correct expression for capacitance of a multi plate capacitor?(a) C=absolute permittivityA/d(b) C=Actual permittivity(n-1)A/d(c) C=Actual permittivity(n)A/d(d) Actual permittivity(n+1)*A/dI had been asked this question during an internship interview.I'm obligated to ask this question of Capacitance of a Multi Plate Capacitor in division Capacitance and Capacitors of Basic Electrical Engineering
Answer» CORRECT OPTION is (b) C=Actual permittivity(n-1)A/d Best explanation: The correct expression is: C=Actual permittivity(n-1)A/d. Where, n=number of plates, A=area of CROSS SECTION of the plates, d=distance of SEPARATION between the plates.
