Capacitance is the ability of a capacitor to store electric charge. It measures how much charge can be stored per unit voltage and depends only on the capacitor's geometry and the dielectric material between the plates.
Use the formula C = k × ε₀ × A / d, where k is the dielectric constant, ε₀ is the permittivity of free space (8.854 × 10⁻¹² F/m), A is the plate area, and d is the separation distance.
With air as the dielectric (k ≈ 1), the capacitance would be approximately 8.85 nF. This is calculated as C = 1 × 8.854 × 10⁻¹² × 1 / 0.001 = 8.854 × 10⁻⁹ F.
A capacitor is the physical device that stores electric charge, while capacitance is the property that quantifies how much charge the capacitor can store per unit voltage.
Materials with higher dielectric constants produce higher capacitance. Ceramics (6-10), glass (4.7), and FR4 (4.2) provide much higher capacitance than air (1.0) or Teflon (2.1).
Capacitance is inversely proportional to plate separation distance. Reducing the distance between plates increases capacitance, while increasing distance decreases it.
