A parallel-plate capacitor has plates of area 0.80 m² separated by a distance of 3.0 mm. What is this capacitor's capacitance?

Question

Quizplus · Accepted Answer

The capacitance of a parallel-plate capacitor is given by the formula C = ε₀(A/d), where ε₀ is the permittivity of free space (8.85 × 10⁻¹² F/m), A is the area of the plates, and d is the separation between the plates. Substituting the given values, C = (8.85 × 10⁻¹² F/m)(0.80 m²)/(3.0 × 10⁻³ m) = 2.4 × 10⁻⁹ F.
