Electronics and Communication Engineering (ECE) : Electromagnetic Field Theory - Quiz(MCQ)
Calculate the capacitance of a material in air with area 20 units and distance between plates is 5m.
A)
3.536nF
B)
3.536pF
C)
35.36pF
D)
35.36nF

Correct Answer : Option (C) :   35.36pF


Explanation : 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.
