  1. AC Voltage in India Explained | Fan Experiment & Concept Demo Understanding AC Voltage in India, Explained helps students grasp everyday electricity concepts. In India, the standard AC Voltage is 220V 50Hz, powering homes, classrooms, and laboratories. This blog fromMajor Kalshi Classes presents a simple Concept Demo using a fan to visualise alternating current, making it perfect for any classroom experiment. ? Key Points & Experiment Steps ● Standard Supply: India's mains provide 220V 50Hz AC voltage. ● Waveform Visualisation: Use an oscilloscope to observe sine waves. ● Fan Demo: Connect a small fan to the AC source to show motor rotation. ● Concept Demo: Note how the current direction changes 50 times per second. ● Classroom Experiment: Safe, low-risk setup with clear wiring and insulation. ● Real‑World Relevance: Highlights why fans, lights, and appliances work. ✅ Conclusion By exploring AC Voltage in India, explained through this fan-based Concept Demo at MKC JEE Classes, learners see theory come to life. The 220V 50Hz supply and alternating nature
