Chapter 12: Electricity and Circuits

The twelfth chapter of Class 6 Science, Electricity and Circuits, introduces students to the basics of electricity and how simple circuits work. Electricity is an essential part of modern life, and this chapter builds the foundation for understanding how electrical energy is produced, transferred, and used.

The chapter begins with sources of electricity such as cells and batteries. A simple electric cell is shown as having two terminals—positive and negative. When connected properly with wires, the cell supplies current that can light a bulb or run a small device. Students also learn about electric circuits, which are pathways through which electricity flows. The chapter explains the difference between open and closed circuits: a bulb glows only in a closed circuit, but not in an open one. It also highlights conductors and insulators. Materials like copper and aluminium allow electricity to pass through and are called conductors, while materials like rubber, wood, or plastic do not conduct electricity and act as insulators. The importance of insulators in keeping us safe while using electricity is emphasized. With NCERT Solutions for Class 6 Science, students can answer textbook exercises on circuit diagrams, cell connections, and examples of conductors and insulators. The NCERT Exemplar for Class 6 Science Solutions provides higher-level practice with questions such as why bulbs do not glow in open circuits, why cells must be connected properly, or why insulators are used to coat electric wires.

Important points of the chapter include:

Sources of electricity: cells and batteries.
Electric circuits: open and closed.
Conductors and insulators with examples.
Importance of safe use of electricity.

By studying this chapter with NCERT and Exemplar solutions, students gain a practical understanding of electricity, which prepares them for more advanced topics in physics and everyday problem-solving.
