Chapter 12- Electricity

Comprehensive Study of Electricity Chapter!

Electricity is the movement of the electrons in the conductors. This form of energy offers power to our appliances. The science behind this topic includes various concepts that CBSE curriculum provides in class 10th.

ScoreX™ allows you to study better with the course of the ncert solutions for class 10 Science Electricity. Our course covers all the topics associated, which are in your CBSE curriculum.

What is the format of this chapter course?

In this course of the CBSE class 10 Science Electricity, we help you learn the following topics:

1. Electric Current and Circuit

The flow of charge in a closed network of conductors is called an electric current. The circuit is the closed network of conductors that provides the frame for the current to flow.

2. Electric Potential and Potential Difference

The electric potential is the work required to move a unit positive charge. The flow of charge always depends on the potential difference between two points.

3. Current Diagram

It is the way of presenting the flow of current with the help of symbols and signs.

4. Ohm’s Law

The law allows creating a relationship between the voltage and the current with the resistance as the relation constant.
