The magnitude of the current at resonance in the LC circuit is estimated using resonance curves (Fig.) or using the formula #### Resonance occurs when the frequency w of the disturbing force becomes exactly equal to the natural frequency of the LC circuit. In mechanical systems consisting of a spring and an oscillating mass, resonance occurs when the frequency of the disturbing force only approaches the natural frequency of the system, but is not exactly equal to it. Is there a violation of the principle of correspondence here?
