What is the capacitance of a parallel plate capacitor with an area of 0.01 m² and a separation of 0.001 m, filled with a dielectric of relative permittivity 5?
Step 1: Identify the formula for the capacitance (C) of a parallel plate capacitor: C = ε₀ * ε_r * A / d.
Step 2: Determine the values needed for the formula: ε₀ (the permittivity of free space) is approximately 8.85 × 10^-12 F/m, ε_r (the relative permittivity of the dielectric) is 5, A (the area of the plates) is 0.01 m², and d (the separation between the plates) is 0.001 m.
Step 3: Substitute the values into the formula: C = (8.85 × 10^-12 F/m) * 5 * (0.01 m²) / (0.001 m).
