Calculation of Capacitance of a Flat Air Capacitor

To find the capacitance of a flat air capacitor, we need to know the area of the plates and the distance between them. In this case, the area of the plates is given as 0.2 m², and the distance between the plates is given as 0.1 m.

The capacitance of a parallel plate capacitor can be calculated using the formula:

C = ε₀ * A / d

Where: - C is the capacitance of the capacitor, - ε₀ is the permittivity of free space (approximately 8.854 x 10⁻¹² F/m), - A is the area of the plates, and - d is the distance between the plates.

Let's substitute the given values into the formula to calculate the capacitance:

C = (8.854 x 10⁻¹² F/m) * (0.2 m²) / (0.1 m)

Calculating this expression gives us the capacitance of the capacitor in farads (F). However, the question asks for the capacitance in picofarads (pF). To convert farads to picofarads, we can use the conversion factor:

1 F = 10¹² pF

Let's calculate the capacitance and convert it to picofarads:

C = (8.854 x 10⁻¹² F/m) * (0.2 m²) / (0.1 m) = 1.7708 x 10⁻¹² F

Converting to picofarads:

C = 1.7708 x 10⁻¹² F * 10¹² pF/F = 1.7708 pF

Therefore, the capacitance of the flat air capacitor is approximately 1.7708 picofarads.

Please note that the calculations provided above are based on the given information and assumptions about the properties of the capacitor.
