please help me!
There is a capacitor C1 constructed by a pair of paralleled conductive plates 20 mm by 50 mm, spacing distance of 10 mm, and a ceramic dielectric with a relative permittivity of εr = 7500 (the absolute dielectric constant of vacuum or air ε0 = 8.85 ⨯ 10-12 F/m). Calculate the following:
a) Capacitance of this capacitance C1.
b)Construct another capacitor C2 with all the same conditions as C1 except the Doubled plate spacing distance. Calculate the total capacitance of these two capacitors C1 and C2 in Parallel.
c) Calculate the total capacitance of these two capacitors C1 and C2 in Series.
