NCERT Solutions for Class 7 Science Chapter 14 – Electric Current and Its Effects

 

Let us start reading the preparation article Regarding CBSE 7 Class

NCERT Solutions for Class 7 Science Chapter 14 - Electric Current and Its Effects: This chapter is very interesting as in this you will study the electric current, its flow, and its effect. It is convenient to represent electric components by symbols. Using these, an electric circuit can be represented by a circuit diagram. When an electric current flows through a wire, the wire gets heated. It is the heating effect of current. This effect has many applications. Wires made from some special materials melt quickly and break when large electric currents are passed through them. These materials are used for making electric fuses which prevent fires and damage to electric appliances. When an electric current flows through a wire, it behaves like a magnet. A current-carrying coil of insulated wire wrapped around a piece of iron is called an electromagnet.

Here are the important topics of NCERT Solutions for Class 7 Science Chapter 14 - Electric Current and Its Effects mentioned below:

14.1 Symbols of Electric Components

14.2 Heating Effect of Electric Current

14.3 Magnetic Effect of Electric Current

14.4 Electromagnet

14.5 Electric Bell

You all are quite familiar with an electric bell. It has an electromagnet in it. It consists of a coil of wire wound on an iron piece. The coil acts as an electromagnet. An iron strip with a hammer at one end is kept close to the electromagnet. There is a contact screw near the iron strip. When the iron strip is in contact with the screw, the current flows through the coil which becomes an electromagnet. It, then, pulls the iron strip. and more about this you will study in this chapter.

After going through this chapter, you must be able to get the NCERT Solution of these questions which are mentioned below, as these questions are from the Science book of NCERT.

Q1. Name any two effects of electric current.

Q2. When the current is switched on through a wire, a compass needle kept nearby gets deflected from its north-south position. Explain.

Q3. An electrician is carrying out some repairs in your house. He wants to replace a fuse by a piece of wire. Would you agree? Give reasons for your response.
