Study notes
Calculate the capacitance of a parallel plate capacitor with plate area A = 2 m², separation d = 0.01 m, and a dielectric with constant K = 4. Formula: C = K * ε₀ * A / d. Given ε₀ = 8.85 x 10⁻¹² F/m. Step 1: Calculate C without dielectric: C₀ = (8.85 x 10⁻¹² * 2) / 0.01 = 1.77 x 10⁻⁹ F. Step 2: Multiply by K: C = 4 * 1.77 x 10⁻⁹ = 7.08 x 10⁻⁹ F. Final Answer: 7.08 nF.
