1.	Calculate the capacitance of a material in air with area 20 units and distance between plates is 5m.(a) 35.36pF(b) 3.536pF(c) 35.36nF(d) 3.536nFThe question was posed to me during an internship interview.Question is from Real Time Applications in division Electrostatic Fields of Electromagnetic Theory
Answer» RIGHT OPTION is (a) 35.36pF To ELABORATE: The capacitance of any MATERIAL is GIVEN by, C = εA/d, where ε = εoεr is the permittivity in air and the material respectively. Thus C = 1 X 8.854 X 10^-12 X 20/5 = 35.36pF.
