Flat air capacitor plates with an area of S = 150 cm ^ 2 and the spacing d = 6 mm charged up to U = 400 V. To determine how to change the electric capacity and energy of the capacitor, if parallel to the plates add metal plate thickness a = 1 mm.
Detailed solution shorthand terms, formulas and laws used in the decision, the withdrawal of the calculation formula and the response.
