What Is Electric Current? (1961)

Explains electric current, highlighting that it originates from a battery and requires a complete circuit to flow. It compares electric current to water flowing through pipes, using meters to demonstrate current flow. The video illustrates that electric charges are already present in wires and can be pushed by a battery to create an electric current. It emphasizes that electric charges exist in all materials, not just wires, and provides a caution regarding experimentation with electric circuits.
