An ideal air-filled parallel plate capacitor with plate a separation of 4.0 cm has a plate area of 0.040 m².What is the capacitance of this capacitor with air between these plates? (ε₀ = 8.85 × 10^-12C²/N ∙ m²)

Question

Quizplus · Accepted Answer

The capacitance of an air-filled parallel plate capacitor is given by the equation C = εA/d, where ε is the permittivity of free space, A is the area of the plate, and d is the distance between the plates. Substituting the given values, we get C = (8.85 × 10^-12 N^-1 m^-2) * (0.040 m^2) / (4.0 cm = 0.04 m) = 8.9 pF. Therefore, the best choice is B.
