Ans:
(a) True
(b) False
(c) False
3. Explain why the bulb would not glow in the arrangement shown in Fig.
Ans: The bulb will not light since the circuit is broken due to the insulator in the middle.
4. Complete the drawing shown in Fig, to indicate where the free ends of the two wires should be joined to make the bulb glow.
Ans :
5. What is the purpose of using an electric switch? Name some electrical gadgets that have switches built into them.
Ans: A switch is a basic device that completes or breaks a circuit in an electric circuit. Electric fans, electric irons, toasters, and other electric appliances need switches.
6. Would the bulb glow after completing the circuit shown in Fig in the Q.4 if instead of a safety pin we use an eraser?
Ans: No, because the eraser is an insulator.
7. Would the bulb glow in the circuit shown in Fig. in Question 04?
Ans: No, the bulb will not glow.
8. Using the “conduction tester” on an object it was found that the bulb begins to glow. Is that objected to by a conductor or an insulator? Explain.
Ans: Because electricity can only pass through a conductor and not through an insulator, that object is called a conductor. The bulb will not glow unless the thing is a conductor.
9. Why should an electrician use rubber gloves while repairing an electric switch at your home?
Ans: Rubber gloves are used as insulators. This prevents the electrician from being electrocuted. That is why, when repairing an electric switch, an electrician wears rubber gloves.
10. The handles of the tools like screwdrivers and pliers used by electricians for repair work usually have plastic or rubber covers on them. Can you explain why?
Ans: Plastic and rubber are both poor electrical conductors. As a result, they protect from electric shock.

The NCERT Solutions of Chapter 12 of Class Science covers a detailed discussion about electricity and circuits. This chapter explains the concepts of electricity, different electrical devices, electrical circuits, conductors, switches, insulators, etc.
This chapter has a total of five sub-topics. It begins with a general introduction to the above-mentioned concepts and then moves on to explain electric cells, circuits, switches, etc. Along with these, the chapter summary and technical terms, given at the end of the chapter also help the students to understand the concepts comprehensively. NCERT Solutions Class 6 Science Chapter 12 offer a concise solution for the understanding of students. NCERT Solutions for Class 6 Science Chapter 12 are available online in PDF format for students to download them. Furthermore, they do not incur any charges.
Important Topics
Important topics that are covered in NCERT Solutions for Class 6 Science Chapter 12 Electricity and Circuits are as follows:
- Electric cell
- Electricity and circuits
- A bulb connected to an electric cell
- An electric circuit
- Electric switch
- Electric conductors and insulators
Important Points to Remember
- To complete or break a circuit, electric switches are utilised. Refrigerators, fans, microwave ovens, televisions and electric cookers are just a few examples of electrical appliances with built-in switches. The NCERT Solutions include diagramatic representations to help students learn key ideas more effectively. To assist pupils in learning the Chapter, the instructor uses easy and accessible terminology. The solutions are written in a systematic manner to ensure that students improve their problem-solving skills, which is necessary for them to feel confident when taking the exam.
- Our bodies carry electricity well, but rubber acts as an insulator. If the body comes into contact with a current carrying wire during repair work, there will be no accident because rubber does not allow electricity to pass through it. As a result, when repairing an electric switch, electricians use rubber gloves.
- Plastic or rubber acts as an insulator, preventing electric current from flowing through it. The handles of instruments used by electricians for repair, such as screwdrivers and pliers, have a coating of plastic or rubber to prevent electric current from passing through these tools and harming the electrician.
NCERT Solutions for Class 6 Science Chapter 12 Topic-Wise Discussion
There are a total of 5 sub-sections in chapter 12. Here is a topic-wise description of each of them.
The lesson 12 Science class 6 begins with an introduction to the topic of electricity and circuits. It starts with how electricity is essential in our daily life, and which devices rely on it to function.
Electric Cell
Class 6 Science chapter 12 explains the concept of the electric cell. It covers the functionality of different electric cells, their architecture, and the hazard sign that one can see on them.
When students understand the working principle of these cells, they can move on to the experiments. There are two DIY activities that students can perform at their home. The first one includes understanding the architecture of a torch bulb. Candidates can take out the bulb and study various parts of it. The filament, for instance, provides the light, with the help of an electric cell.
Bulb Connected to an Electric Cell
In the following section of electricity and circuits class 6, students learn how to light a torch bulb using an electric cell. This section includes a step-by-step guide on how to execute this process successfully.
Students can take two electric wires of different colours and cut-off their plastic covering to bring out their metal cores. After that, they need to join one end of the exposed metal portion with the cell and the other one with the bulb. They can use tape used by electricians to stick them.
Students can then experiment by interchanging the wires and note down the results to discuss later.
Electric Circuit
As the name suggests, this chapter in NCERT class 6 Science chapter 12 presents a detailed understanding of electrical circuits. Taking a cue from the previous experiment, students had already learned the basics of an electrical circuit when they lighted a torch bulb with an electrical cell.
In the previous experiment, they created an electrical circuit by joining this electrical cell with a torch bulb. They created a clear path where the electricity is passed between two terminals of electric cells. Class 6th Science Chapter 12 further provides a DIY project that students can perform to improve their understanding of a fundamental electrical circuit.
Electric Switch
Class 6 Science ch 12 then discusses the concept of an electric switch. Electric switches are mandatory in an electrical circuit as they control the flow of electricity with that particular circuit.
There is an activity mentioned in this section that students can perform to improve their understanding of electrical switches further. This activity includes the usage of some household materials like Thermo Col or wooden board, paper clips, safety pins, etc. to create a circuit and an electrical switch.
Electric Conductors and Insulators
Electricity and circuits class 6 NCERT Solutions discuss different conductors and insulators. This topic begins with an example from the previous experiment and discusses how metal is a good conductor of electricity.
After that, NCERT Solutions for class 6 Science Chapter 12 move on to a detailed discussion about various objects and their ability to transport electricity. After that, candidates learn about insulators, how they function, and their importance in an electrical circuit.
