NCERT Solutions for Class 10 Science, Chapter 12 - Electricity

In this chapter, you’ll study yet another important concept in Physics – Electricity. We
all are aware of how important electricity is in our everyday lives. In fact, in the modern
era, it is impossible to stay without electricity. It is a form of energy that is used
wherever we go and almost in whatever we do. The mobiles we use, the laptop we
charge, the air conditioners we switch on, the washing machine in our homes, all run on
electricity! However, have you ever wondered how this electricity is formed? How it is
regulated?

In NCERT Solutions for Class 10 Science, Chapter 12, you’ll study about electric
current, the circuit, and potential of electricity, how the circuit diagram looks, what are
resistors, heating effect and its applications, and much more.

Let’s take a look at topics and sub-topics of class 10 Science Chapter 12, Electricity

12.1 Electric Current and Circuit
12.2 Electric Potential and Potential Difference
12.3 Circuit Diagram
12.4 Ohm’s Law
12.5 Factors on which the resistance of a conductor depends
12.6 Resistance of a system of resistors
12.6.1 Resistors in Series
12.6.2 Resistors in Parallel

In Class 10 Science Chapter 12, you will learn – 

Section 12.1 – In this section, you’ll study the electric current and circuit with
the help of a schematic diagram of an electric circuit consisting of a cell, electric bulb,
ammeter and plug key.

Section 12.2 – In this section, you’ll learn what you mean by a voltmeter, electric
potential and the potential difference between two points.

Section 12.3 – In this section, you’ll learn about the circuit diagram and symbols of
some commonly used components in circuit diagrams.

Section 12.4 – In this section, you’ll acquire knowledge about the findings of the
German physicist – Georg Simon Ohm. You’ll study Ohm’s Law with the help of an
activity. You’ll also learn about related terms like variable resistance and rheostat.

Section 12.5 – In this section, you’ll learn about the factors on which the resistance of a
conductor depends. You’ll also observe the electrical resistivity of some substances at
20°C.

Section 12.6 – In this section, you’ll study about resistance, what resistors are, resistors
in series and resistors in parallel. You’ll learn what happens to the value of current
when a number of resistors are connected in series in a circuit with the help of certain
activities.

Section 12.7 – In this section, you’ll learn about the heating effect of electric current
and practical applications of heating effect of electric current.

Section 12.8 – In this section, you’ll study what electric power is and how it is
measured.
