Example of capacitor charge remaining unchanged
Charge, usually denoted by (Q), is measured in coulombs (C). The accumulation of charge on a capacitor''s plates creates an electric field, which is responsible for the energy-storing capability of the capacitor. In a scenario where a capacitor is connected to a battery and then disconnected, the charge on the plates remains constant.
