Factors Affecting Resistance | Electric Current | Class 10 SSC Physics 2026 | Part 6 | Numericals

In this video, we continue Class 10 SSC Physics – Electric Current (Part 6) and understand: 👉 Factors Affecting Resistance This topic is very important for SSC Board Exams 2026 and is frequently asked in theory as well as numerical problems. 📌 Topics Covered: ✔️ What is Resistance? ✔️ SI Unit of Resistance (Ohm – Ω) ✔️ Factors Affecting Resistance ✔️ Length of Conductor ✔️ Area of Cross-Section ✔️ Nature of Material (Resistivity) ✔️ Effect of Temperature ✔️ Formula: R = ρL/A ✔️ Simple Numericals 🎯 Key Concepts: 🔹 Resistance (R): Opposition offered by a conductor to the flow of electric current. 🔹 Resistance depends on: 1️⃣ Length (L) → More length → More resistance 2️⃣ Area (A) → More area → Less resistance 3️⃣ Material (ρ – Resistivity) → Different materials have different resistivity 4️⃣ Temperature → For metals, resistance increases with temperature 👉 Formula: R = ρL / A Where, R = Resistance ρ = Resistivity L = Length A = Area of cross-section 📚 Important Exam Questions: 1. Define resistance. 2. Write the factors affecting resistance. 3. Write the formula for resistance. 4. How does temperature affect resistance? 5. Solve numericals based on R = ρL/A. 📌 This topic is very important for understanding Ohm’s Law and solving circuit problems. 🔗 Part 1 Link: ___________________ 🔗 Part 2 Link: ___________________ 🔗 Part 3 Link: ___________________ 🔗 Part 4 Link: ___________________ 🔗 Part 5 Link: ___________________ 👍 Like the video 📢 Share with your classmates 🔔 Subscribe for more Class 10 SSC Physics lessons
