Alternating Current Class 12 Physics | AC vs DC, Peak, Instantaneous, Average & RMS Value Derivation

Welcome to Saksham Classes! In this live session, we are starting Class 12 Physics Chapter 07: Alternating Current (A.C.) - Lecture 01. In this class, we will cover all the foundational concepts, important wave types, and step-by-step mathematical derivations required for your board exams. 📚 Topics Covered in this Lecture: Direct Current (D.C.) vs Alternating Current (A.C.) – Detailed Comparison Types of Wave Currents: Square Wave, Triangular Wave, and Sinusoidal Wave Current Instantaneous Value of A.C. and Voltage Peak Value (Amplitude) of A.C. Average (Mean) Value of A.C. (Complete Derivation for Full Cycle and Half Cycle) Root Mean Square (R.M.S.) / Effective Value of A.C. (Complete Derivation: $I_{rms} = 0.707 I_0$) Why 220V A.C. is more dangerous than 220V D.C.? Advantages & Disadvantages of A.C. over D.C. 📢 Join Our Community & Get PDF Notes: Telegram Channel: t.me/saksham_classes25 WhatsApp Channel: Saksham Classes Official :#Class12Physics #AlternatingCurrent #ACvsDC #RMSValue #PhysicsDerivations #SakshamClasses #VijayJiSir #BoardExam2027
