Charge (physics)

In physics, "charge" refers to the property of a particle that determines its electromagnetic interactions. It is a fundamental characteristic of certain subatomic particles, most notably electrons and protons, which exhibit electric charge. There are two types of electric charge: positive and negative. 1. **Positive Charge**: Carried by protons. When two objects with positive charges are brought close to each other, they repel each other. 2. **Negative Charge**: Carried by electrons.
