1. Electrical Resonance What is Resonance? In an AC circuit, electrical resonance is a condition where the inductive reactance (X_C) become equal, canceling each other out. This leaves only the circuit resistance (X_L = 2πfL): Opposition from inductors (e.g., motors, transformers). Increases with frequency. Capacitive Reactance (f_r) This is the specific frequency where f_r = 1 / (2π√(LC)) Wh...
