What happens when inductive and capacitive reactance are equal in a series LC circuit?

In a series LC (inductor-capacitor) circuit, inductive reactance and capacitive reactance cancel each other out when they are equal. This specific condition is known as series resonance. Because these two reactances are exactly opposite in phase, their combined reactive opposition to alternating current drops to zero. Consequently, the total impedance of the circuit reaches its minimum possible value, limited only by the pure resistance of the wire and components. Distractors often try to confuse series and parallel circuits; while a parallel LC circuit has very high impedance at resonance, a series LC circuit has very low impedance.
