Electric Circuits Unplugged: Exploring Components and Functions

In this video, Mr. Ngongo introduces the concept of electric circuits, explaining that electricity is a form of energy that can be converted into other useful forms. He describes a circuit as a path for currency flow and discusses the symbols used in electric circuits, such as connecting wires, cells, batteries, and switches. The video also covers the components of a simple circuit and the function of a switch in controlling the flow of currency. The session concludes with a preview of the next topic, which will cover series and parallel circuits.
