In the context of electricity, what is the movement of invisible particles called?

The movement of invisible particles in the context of electricity refers to the flow of electric charge, primarily carried by electrons in a conductor. This flow is measured as current, which is the rate at which charge is transferred across a point in a circuit. Essentially, current represents the movement of these charged particles, allowing for the transmission of electrical energy to power devices and systems.

In contrast, voltage refers to the potential difference that drives the movement of electrons, resistance relates to the opposition to the flow of current in a circuit, and power is the rate at which electrical energy is consumed or produced. Current specifically encapsulates the concept of the flow of these invisible particles, making it the most accurate term in this context.
