Question

 (I) What is the capacitance of a pair of circular plates with a radius of 5.0 cm separated by 3.2 mm of mica?

Answer 1

Answer:

1.3 x 10^-10 F

Explanation:

r = 5 cm = 0.05 m, d = 3.2 mm = 0.0032 m

Dielectric constant for mica, K = 6

The formula for the parallel plate capacitor is given by

C = K ∈0 A /d

C = (6 x 8.854 x 10^-12 x 3.14 x 0.05 x 0.05) / 0.0032

C = 1.3 x 10^-10 F
