# A parallel-plate air-filled capacitor has a capacitance of 43 pF.?

A parallel-plate air-filled capacitor has a capacitance of 43 pF. (a) If each of its plates has an area of 0.28 m2, what is the separation? (b) If the region between the plates is now filled with material having κ = 8.2, what is the capacitance?

43 pF = 0.000043 microF

using the equation C=(k*epilison*Area)/separation

where,

epsilon = 8.854*10^-12 F/m

C= 43 pF

A=0.28

k=1.0

solve for d (separation)

d=5.765 cm

b)

C = (8.2*0.28*8.854*10^-12)/(0.05765)

C = 3.525*10^-10 F = 352.5 pF
