NCERT Solutions For Class 6 Science Chapter 12 Electricity and Circuits in Hindi - 2025-26

Q: 5. What is the function of the filament in an electric bulb as explained in Chapter 12?

According to the concepts in this chapter, the filament is a very thin wire inside the electric bulb. Its primary function is to glow when electric current passes through it. This heating effect produces light. If the filament is broken, the path for the current is incomplete, and the bulb is considered fused, meaning it will no longer light up.

FAQs on NCERT Solutions For Class 6 Science Chapter 12 Electricity and Circuits in Hindi - 2025-26

1. What are the key concepts covered in the NCERT Solutions for Class 6 Science Chapter 12, 'Electricity and Circuits'?

The NCERT Solutions for Class 6 Science Chapter 12 explain the fundamental concepts of electricity and circuits. Key topics include the electric cell as a source of electricity, the structure and function of an electric bulb including its filament, the definition and components of an electric circuit, the role of an electric switch, and the difference between materials that are conductors and insulators of electricity.

2. How should one solve the NCERT exercise that requires drawing a labelled diagram of an electric circuit?

To correctly solve the diagram-based question as per the NCERT solutions, follow these steps:

First, draw the symbol for an electric cell, ensuring you mark the positive (+) and negative (-) terminals.
Next, draw the symbol for an electric bulb.
Include an electric switch in the 'ON' or closed position to show a complete circuit.
Finally, connect all components using straight, continuous lines that represent the connecting wires, ensuring there are no gaps in the path.

3. Using the logic from NCERT Solutions, if a conduction tester's bulb glows, is the object a conductor or an insulator? Explain the method.

If the bulb of the conduction tester glows, the object is a conductor. The correct explanation is that a conductor allows electric current to pass through it freely. By placing the object in the tester's circuit, it completes the path for electricity to flow from the cell to the bulb, causing the filament to heat up and glow. An insulator would block this flow and the bulb would not light up.

4. What is the correct way to solve the 'fill in the blank' questions from the NCERT textbook for Chapter 12?

To solve the fill-in-the-blank questions, you must use the precise terminology from the chapter. For example, for the statement, "A device that is used to break an electric circuit is called a ______," the correct answer is a switch. The NCERT solutions provide the exact terms for each blank, reinforcing the key definitions required for the CBSE 2025-26 syllabus.

5. What is the function of the filament in an electric bulb as explained in Chapter 12?

According to the concepts in this chapter, the filament is a very thin wire inside the electric bulb. Its primary function is to glow when electric current passes through it. This heating effect produces light. If the filament is broken, the path for the current is incomplete, and the bulb is considered fused, meaning it will no longer light up.

6. When solving problems, why might a bulb not glow even when connected to a cell in a circuit?

There are several reasons, based on the principles of electric circuits, why a bulb may not glow. The NCERT solutions help troubleshoot these common issues:

The circuit might be open, meaning there is a break or a loose connection in the path.
The bulb's filament might be broken, making the bulb 'fused'.
The electric cell might be used up or exhausted, and can no longer provide electricity.
The connections to the terminals of the cell or bulb might be incorrect.

7. Why is it essential for an electric circuit to be a 'closed loop' for electricity to flow?

It is essential for an electric circuit to be a closed or complete loop because electric current needs a continuous and unbroken path to travel. The flow starts from the positive terminal of the electric cell, moves through the wires and components like the bulb and switch, and must return to the negative terminal of the same cell. Any gap or break creates an open circuit, which stops the flow of electricity instantly.

8. How does an electric switch work to control a circuit, based on the principles in this chapter?

An electric switch is a simple device that functions by either completing or breaking a circuit. In the 'ON' position, it acts as a bridge, closing the gap in the circuit and allowing electricity to flow through it. In the 'OFF' position, it creates a deliberate gap in the circuit, which interrupts the path and stops the flow of electricity, thus turning the appliance off.

9. What is the fundamental difference between conductors and insulators, and why are both important for electrical safety?

The fundamental difference is how they interact with electricity. Conductors, like copper and aluminium, allow electric current to pass through them easily. Insulators, like plastic, rubber, and wood, do not allow current to pass. Both are crucial for safety; conductors are used for the wires to carry current, while insulators are used to cover the wires and switches to protect us from electric shocks.

10. Where can I find reliable, step-by-step NCERT Solutions for Class 6 Science Chapter 12 for the 2025-26 session?

You can find comprehensive, step-by-step NCERT Solutions for Class 6 Science Chapter 12, fully aligned with the CBSE 2025-26 syllabus, on trusted educational platforms like Vedantu.
