A parallel plate capacitor is constructed of two circular disks, radius 5.26 cm, sharing a common axis. If the air-gap separation distance between them is 2.39 mm, what is the effective capacitance, in pF?
Here ,
distance between plates , d = 2.39 mm = 0.00239 m
r = 5.26 cm = 0.0526 m
effective capacitance = epsilon * Area/distance
effective capacitance = 8.854 *10^-12 * pi * 0.0526^2/0.00239
effective capacitance = 3.22 *10^-11 F
effective capacitance = 32.2 pF
the effective capacitance is 32.2 pF
