The model helps to understand the principle of movement of electric current in a circuit.

The charged particles are in a limited area of the ring, and under the action of an external force along the chain, they act on each other. Collective interaction causes the ordered movement of charged particles in the model conductor.

In the interactive model, it is proposed to control the external force (voltage) and the coefficient of energy dissipation (resistance) in order to observe how the speed of movement of charged particles (current) will change.
