BEEE Unit 6: Single Phase AC Series Circuits – R-L-C Theory, Phasors & Resonance
Detailed, exam-oriented handwritten notes for Unit 6 of Basic Electrical & Electronics Engineering (BEEE). This chapter covers the complete analysis of AC series circuits, essential for first-year engineering students. Key Topics Covered: Pure Circuits: Comprehensive analysis of purely Resistive (R), Inductive (L), and Capacitive (C) circuits, including instantaneous power derivations and phase relationships. Series Combinations: Step-by-step theory, impedance calculations, and phasor diagrams for R-L, R-C, and R-L-C series circuits. Power Analysis: Definitions, formulas, and units for Apparent Power (S), Active Power (P), and Reactive Power (Q). Series Resonance: Detailed derivation of Resonant Frequency (f_r), current behavior at resonance, and impedance minimization. Quality & Bandwidth: Formulas and explanations for Q-factor (Voltage magnification) and Bandwidth (B.W.) of resonant circuits. Solved Examples: Practical numerical problems calculating Resistance, Inductance, Capacitance, Power Factor, and Voltage drops.
