एक श्रेणी LCR सर्किट में अनुनाद (resonance) के संबंध में निम्नलिखित में से कौन सा कथन सही नहीं है?

In an Alternating Current (AC) circuit, match Column-I (Type of Circuit) with Column-II (Phase Relationship between Current and Voltage): Column-I i. Pure Resistance (R) ii. Pure Capacitance (C) iii. Pure Inductance (L) iv. R-L-C Series Circuit Column-II p. Current leads voltage by 90° q. Current and voltage are in the same phase r. Phase relationship depends on circuit parameters (θ != 0°) s. Current lags voltage by 90°

In a real-world series RLC circuit where resistance (R) is nonzero, the total impedance at resonance is ________.
