Electric Circuits and Components

In this video tutorial, Teacher Roska introduces the topic of Electric City from Unit 7, guiding students through the identification and explanation of electrical components. The lesson covers the importance of electricity, the components needed for a complete electric circuit, and the specific functions of each component, such as dry cells, bulbs, switches, and connecting wires. The session concludes with a summary of the key points discussed.
