The area of the air condenser plate is 15 cm2, and the distance between the plates is 0.02 cm.

The area of the air condenser plate is 15 cm2, and the distance between the plates is 0.02 cm. What is the capacitance of the capacitor?

Data: S (plate area of the air condenser taken) = 15 cm2 (15 * 10-4 m); d (distance between plates) = 0.02 cm (0.02 * 10-2 m).

Constants: ε (relative dielectric constant of air) = 1.0006; ε0 (electrical constant) = 8.85 * 10-12 F / m.

The capacity of the air condenser taken is determined by the formula: C = ε * ε0 * S / d.

Calculation: C = 1.0006 * 8.85 * 10-12 * 15 * 10-4 / (0.02 * 10-2) ≈ 66.4 * 10-12 F (66.4 pF).

Answer: The capacitance of the capacitor is 66.4 pF.
