Скачать или смотреть Electric Power & Overloading | Electric Current | Class 10 SSC Physics 2026 | Part 9 | Numericals

In this video, we complete the chapter Class 10 SSC Physics – Electric Current (Part 9) with two important topics:

👉 Electric Power
👉 Overloading in Electric Circuits

These concepts are very important for SSC Board Exams 2026 and are frequently asked in numericals and theory questions.

📌 Topics Covered:

✔️ What is Electric Power?
✔️ Formula of Electric Power (P = VI)
✔️ Power in terms of Resistance (P = I²R, P = V²/R)
✔️ SI Unit of Power (Watt)
✔️ Commercial Unit of Electrical Energy (kWh)
✔️ What is Overloading?
✔️ Causes of Overloading
✔️ Safety Devices (Fuse & MCB – basic idea)


🎯 Key Concepts:

🔹 Electric Power (P):
Rate at which electrical energy is consumed or work is done.

👉 P = V × I

🔹 1 kWh = 1 Unit of Electricity

🔹 Overloading:
Occurs when current flowing in a circuit exceeds the safe limit, causing overheating and possible fire hazards.

📚 Important Exam Questions:
1. Define electric power.
2. Write different formulas of electric power.
3. What is overloading?
4. What are the causes and prevention methods of overloading?
5. Solve numericals based on electric power.

📌 This topic is very important for board exam numericals and daily life applications.
