A positive charge is a fundamental property of matter, typically associated with protons, which are found in the nucleus of an atom. When an object has more protons than electrons, it carries a positive charge. This imbalance creates an electric field that can attract negatively charged objects, such as electrons. In the context of electricity, positive charge plays a crucial role in the behavior of electric circuits. For example, in a battery, the positive terminal is where the positive charge accumulates, allowing it to drive current through a circuit when connected to a load, like a light bulb or a motor.
