Review | Constants Part A A constant potential difference of 12 V is maintained between the terminals of a 0.25 /F, parallel-plate, air capacitor. A sheet of Mylar is inserted between the plates of the capacitor, completely filling the space between the plates. When this is done, how much additional charge flows onto the positive plate For related problem-solving tips and strategies, you may want to view a Video of the capacitor? (Dielectric constant /
