🔍 Key Concepts

• Series reactance in AC circuits (inductive and capacitive reactance) • How voltages can add as phasors, not simple arithmetic sums, in AC • What happens at resonant frequency in an LC series circuit

💭 Think About

• Think about how voltage drops across different reactances in series relate to the applied AC voltage when you consider phase angles, not just magnitudes. • Ask yourself: under what condition could the individual voltage across one or more reactances be higher than the source voltage, even though they are in series? • Which option describes a condition or property that can cause voltage magnification in an AC circuit with inductive and capacitive reactances?

✅ Before You Answer

• Verify which choice refers to a condition in AC circuits rather than a basic material property like resistance or conductance. • Check which phenomenon is associated with voltage magnification and very high circulating currents in a series LC circuit. • Confirm which term is specifically linked to the natural frequency behavior of an LC circuit where inductive and capacitive reactances cancel each other.
