Learning about Electric Current (1955)

The film explains how electric current is generated at power plants and delivered to homes through wires. It describes the concept of electric circuits, including closed and open circuits, and the role of switches in controlling the flow of current. The video demonstrates experiments using dry cells to illustrate the principles of conductors, insulators, and resistance. It also introduces electromagnets, showing how electric current can produce light, heat, and motion, emphasizing the importance of electric current in everyday life.
