An air-filled parallel plate capacitor has a capacitance of 37 pF.

Question

(a) What is the separation of the plates if each plate has an area of 0.8 m2? (cm)

(b) If the region between the plates is filled with a material with κ = 5.0, what is the final capacitance? (pF)

Answer 1

It is a formula..

C=k eo A/d where k is dielectric constant (1 for air, 5.0 for part b)
eo=8.86E-12
