Building a Faraday Cage To Contain EMI, Part 1
Learn MoreEventually, the side where the electrons gather won''t have room for more electrons, so the current stops flowing. When that happens, the capacitor is fully charged. The amount of electric charge the capacitor can hold is called its capacitance. Electrons don''t like being crowded together on one plate.
