🚀 Motion of a Body in a Lift (Elevator)
👉 Basic Concept: When a body of mass m is placed on a weighing machine kept inside a lift, its actual weight is: Actual weight = m × g This force (m × g) acts on the weighing machine, which gives a reaction R. The reading of the machine is this reaction R. 📌 Important:This…
🔌 क्या है A.C. Generator?
A.C. Generator एक ऐसी मशीन है जो mechanical energy को electrical energy में बदलती है।इसे एक Yugoslav scientist Nikola Tesla ने डिज़ाइन किया था। ⚙️ Principle (सिद्धांत): A.C. Generator electromagnetic induction के सिद्धांत पर काम करता है। जब किसी coil से गुजरने वाला magnetic flux बदलता है, तो coil में electric current (e.m.f.) उत्पन्न होता…
