The area of the mica capacitor plate is 15 cm ^ 2, and the distance between the plates is 0.02 cm. What is the capacitance of the capacitor?
These tasks: S (area of the plate of the taken mica capacitor) = 15 cm2 (in SI S = 15 * 10 ^ -4 m2); d (distance between plates) = 0.02 cm (in SI d = 0.02 * 10 ^ -2 m).
Constants: ε0 (electrical constant) = 8.85 * 10 ^ -12 Cl2 / (N * m2); ε (dielectric constant of mica) = 6.
The capacity of the taken mica capacitor is calculated by the formula: С = ε * ε0 * S / d.
Let’s perform the calculation: C = 6 * 8.85 * 10 ^ -12 * 15 * 10 ^ -4 / (0.02 * 10 ^ -2) = 398.25 * 10 ^ -12 F (398.25 pF).
