Which term describes the flow of negatively charged particles?

The term that describes the flow of negatively charged particles is "current." In the context of electricity, current refers to the movement of electric charge through a conductor, commonly measured in amperes. When discussing the flow of electricity, the focus is often on the flow of electrons, which carry a negative charge. Therefore, when we say there is current, we are referring to the movement of these negatively charged particles.

Voltage pertains to the difference in electric potential energy between two points in a circuit but does not describe the movement of charge itself. Resistance refers to the opposition that a substance offers to the flow of electric current, impacting how easily current can flow through a particular material, but again, it does not describe the flow. Power, on the other hand, is the rate at which electrical energy is transferred by an electric circuit. It is calculated as the product of voltage and current.

Thus, current is the most accurate term to describe the flow of negatively charged particles.
