Short Answer Questions: 3 Marks

1. How does a light bulb produce light?

Ans: A thin wire like structure known as filament is present inside the bulb. When we switch on the bulb, electricity passes through filament causing it to heat up and glow to produce light. In this process the electric energy changes into light energy.

2. What is an electric circuit?

Ans: The closed path in which electric current flows is called an electric circuit. Generally, an electric circuit consists of wire, battery, switch and an appliance which needs electricity to work. The current in the electric circuit flows from the positive terminal to the negative terminal. The switch is used to break the flow of the current when the appliance is not in use.

3. How does a bulb fuse?

Ans: Inside the bulb there is a thin wire like structure called filament. Filament is made of substances having a low melting point. Filament gets heated and emits light when we switch on the bulb. But when there is excess flow of current through the filament it melts down due to excessive heat. This causes fusing of the bulb.

4. Explain the role of a switch in a circuit. What is it made up of?

Ans: An electric switch is a circuit component that can be used to control the flow of electricity through the circuit. It has the ability to both complete and break the circuit. A conducting substance is used to make the switch. The circuit is complete and power flows through it when the switch is in the "ON" position. The circuit is broken and power cannot flow through it while the switch is in the "OFF" position.

5. Label the parts in the following diagram. Indicate the positive and negative terminals.

Ans:

1. Differentiate between conductors and insulators.

Ans: The differences between conductors and insulators are as follows:

2. In the following diagram explain whether the bulb will glow in each of the cases.

Ans:
a) The bulb will glow as the circuit is complete. 

b) The bulb will not glow as the circuit is incomplete. 

c) The bulb will not glow as the circuit is incomplete. 

d) The bulb will not glow as both wires are connected only to the negative terminal of the cell. 

e) The bulb will not glow as both wires from the bulb are connected only to the positive terminal of the cell. 

f) The bulb will glow as the circuit is complete.

Electricity and Circuits: NCERT Class 6 Science Chapter 12 Summary

You might have come across the term ‘current’ in other chapters of different subjects. A current represents a flow of anything. It can be water, a substance, or wind. Anything that flows can be explained as a current. People flocking in a busy station by forming a line can also be considered as an example of human current. This chapter will explain what a current is and it is defined in the context of electricity. The Important Questions on Electricity and Circuits for Class 6 will be based on these concepts. These questions will also be answered by the top teachers.

Let us check what the chapter will cover and what kind of questions you will find in this file.

Students will learn what current means. They will also learn how the flow of electrons is considered to be an electric current. An electric current has a set of features that you should learn from this chapter. This is when you will develop the foundation of concepts based on electricity. Using this foundation, you will then proceed to learn new advanced concepts in the higher classes related to this chapter.

You will learn how an electric current is formed and flows from the positive terminal to the negative terminal when connected to a battery. For the first time, you will learn what a circuit means. Class 6 Science Chapter 12 Important Questions will be based on those new concepts of this chapter. Make sure you study them well to answer these questions easily. On proceeding further, you will come to know about an electric cell and how it works to generate electricity when connected to a circuit. Certain factors determine the flow of current from one terminal to the other. Find out how an electric cell gets exhausted from use.

In the next section of the chapter, you will study how an electric bulb is connected to a circuit and how it glows using the electric current flowing in it. The various components of the electric circuit along with the bulb will be described and the Important Questions for Class 6 Science Chapter 12 will be based on this topic. Learn how an electric bulb functions when connected to a live circuit. You will also come to know different kinds of wires used in a circuit and what materials are used to make them. Delve deeper into the chapter and learn more about conductors, insulators, keys, switches, resistors, etc.
