Vedclass · Answer

(A) In an $LC$ parallel resonant circuit,at resonance,the inductive reactance $(X_L)$ is equal to the capacitive reactance $(X_C)$.This leads to a condition where the total impedance of the circuit becomes very high (theoretically infinite in an ideal circuit).Because the impedance is very high,the current drawn from the source is minimal.Therefore,the $LC$ parallel resonant circuit acts as a high-impedance circuit at resonance.
