How much will the capacity of a flat air condenser change with the area of the plates S = 10 cm ^ 2

How much will the capacity of a flat air condenser change with the area of the plates S = 10 cm ^ 2 if the distance between the plates is increased from d1 = 1 mm to d2 = 1.5 mm?

Initial data: S (area of the plates of this flat air condenser) = 10 cm2; d1 (initial distance between plates) = 1 mm; d2 (final distance between plates) = 1.5 mm.

The change in the capacitance of this capacitor is determined by the formula: k = C1 / C2 = (ε * ε0 * S / d1) / (ε * ε0 * S / d2) = d2 / d1.

Calculation: k = 1.5 / 1 = 1.5 p.

Answer: The capacity of a flat air condenser will decrease by 1.5 times.
