NCERT Exemplar Class 10 Science Chapter 12 – Electricity
The NCERT Exemplar Class 10 Science Solutions for Chapter 12 – Electricity help students build a strong foundation in one of the most important areas of physics. This chapter introduces the principles of electric current, potential difference, resistance, and energy, which are essential for both theoretical learning and practical applications. With the aid of NCERT Solutions for Class 10 Science, learners can master numerical problems and conceptual questions effectively. The chapter begins by defining electric current as the flow of charges in a conductor. Students learn the relation between current, potential difference, and resistance through Ohm’s Law. The experimental verification of this law is explained step by step, making the concept easy to understand. Graphical representation of current versus voltage is also discussed, helping learners visualize the relationship. Next, the chapter focuses on resistance and factors affecting it, such as the length, area of cross-section, and nature of material of the conductor. The concept of resistivity is introduced along with its practical importance in material selection. Students also explore the combination of resistors in series and parallel, understanding how total resistance, current, and voltage differ in each case.
The chapter further explains electric power and energy consumption, highlighting their relevance in daily life. Students learn to calculate power using formulas and apply these concepts to real-world situations like electricity bills. The practical unit of energy, the kilowatt-hour (kWh), is explained with examples. By solving NCERT Exemplar Class 10 Science exercises, learners gain confidence in handling both numerical and reasoning-based problems. Special emphasis is given to practical applications of electricity, including household circuits, safety measures, and the significance of fuses. These real-life connections make the subject engaging and meaningful. Through NCERT Solutions for Class 10 Science Chapter 12, students practice stepwise solutions for all in-text and exemplar questions. This ensures clarity in solving derivations, numerical problems, and application-based exercises. In conclusion, Chapter 12 equips learners with the knowledge of electricity’s principles and applications. It builds the foundation for advanced studies in physics and engineering while ensuring strong board exam preparation. With NCERT Exemplar Class 10 Science Solutions, students can achieve both conceptual mastery and exam excellence.
