Which concept refers to the interaction and movement of charged particles?

The concept that refers to the interaction and movement of charged particles is current. Current is a measure of the flow of electric charge, typically carried by moving electrons in a conductor. When charged particles, such as electrons, move through a wire or other conductive material, they create an electric current. This movement is essential for the functioning of electrical devices and systems.

Electricity encompasses a broader range of phenomena related to the presence and flow of electric charge, including both current and static electricity. Magnetism, while related to electricity, specifically involves the forces and interactions between magnets and moving charges, rather than the movement of charged particles themselves. Energy transfer refers to the movement of energy from one place to another, which can occur in various forms, including electrical energy but does not specifically focus on the movement of charged particles like current does.
