Problem 29 A parallel-plate capacitor has p... [FREE SOLUTION …
In a parallel-plate capacitor, the capacitance is determined by the area (A) of the plates, the separation distance (d), and the permittivity of the material between the plates (for free space this is (epsilon_0)). The formula for capacitance in this case is: [ C = frac{epsilon_0 A}{d} ] Thus, by increasing the separation between the plates, the capacitance decreases, …
