Question Detail

The capacitance (C) of a parallel-plate capacitor is given by C = ε₀A/d, where ε₀ is the permittivity of free space, A is the area of the plates, and d is the distance between the plates. Given: A = 15 cm² = 15 x 10-4 m², d = 3 cm = 3 x 10-2 m, ε₀ = 8.854 x 10-12 F/m. C = (8.854 x 10-12 F/m) * (15 x 10-4 m²) / (3 x 10-2 m) = (8.854 * 15 / 3) x 10-12-4+2 F = (8.854 * 5) x 10-14 F = 44.27 x 10-14 F = 4.427 x 10-13 F. This rounds to 4.43 x 10-13 F.
