Students are well aware that when an electric current flows through a light bulb, it glows. As their grade increases, they have understood that electric current flows because electric charges move. Since the transfer of electric charges is not visible, students have many cognitive difficulties in understanding this process, and teaching materials for visualization have been developed accordingly. However, in most of their materials, electric charges are represented as dots or circles, so it would be better to call it a model rather than a visualization. We can visualize the transfer of charge by using an LED that turns on during electrostatic induction in the conductor.
