Electricity💡class 10 Part 2 | Ohm’s Law, Resistance & Resistivity Explained #electricity #ohms_law

Welcome to School24x7! In this video, we continue Class 10 Science Chapter 11 – Electricity (Part 2) and study the most important laws and quantities used in electrical numericals — Ohm’s Law, Resistance, and Resistivity. This lecture explains the concepts logically and step-by-step, helping students build confidence in formula application, V–I relationships, and problem-solving, strictly following the NCERT syllabus. 📘 Topics Covered in This Video: 🔹 1. Ohm’s Law Statement of Ohm’s Law Relationship between voltage (V), current (I) and resistance (R) Mathematical form: V = IR Conditions under which Ohm’s law is applicable Limitations of Ohm’s law 🔹 2. Resistance Meaning of resistance Why conductors oppose current SI unit of resistance (ohm) Factors affecting resistance: ✔ Length of the conductor ✔ Area of cross-section ✔ Nature of material ✔ Temperature 🔹 3. Resistivity Meaning of resistivity Relation between resistance and resistivity Formula: R = ρ L / A SI unit of resistivity (ohm-metre) Why resistivity is a property of material Comparison of conductors, semiconductors and insulators 🎯 What You Will Learn: ✔ Clear understanding of Ohm’s law ✔ Difference between resistance and resistivity ✔ Factors affecting resistance ✔ Proper use of formulas in numericals ✔ Strong base for series & parallel circuit problems 📚 Perfect For: Class 10 CBSE & NCERT Students Board exam preparation Students preparing for electricity numericals 🔔 Subscribe to School24x7 for complete NCERT Science & Maths chapter-wise lectures. 👍 Like, Share & Comment your doubts — we’ll clear them step-by-step!
