Simple Capacitor Problems
A conducting sheet of material (see attachment 'a') has a cross-sectional area (l x w) of 10mm x 20 mm. The material has a resistivity of 103 Ω m.
Calculate the thickness, t, of the material required to give a resistance of 5k Ω.
A capacitor is formed by two parallel metal plates separated by a dielectric of relative permittivity, Er = 12 (see attachment 'b').
Calculate the thickness, t, of the dielectric required to create a capacitor of 100pF.
