In a series circuit with equal inductive and capacitive reactance, what is a true statement?

In a series circuit where the inductive reactance and capacitive reactance are equal, the two reactances effectively cancel each other out. This cancellation occurs because inductive reactance (which tends to store energy in a magnetic field) opposes the flow of current in one direction, while capacitive reactance (which stores energy in an electric field) opposes the flow of current in the other direction. When the magnitudes of these reactances are equal, they result in a net reactance of zero.

This balancing of the reactances means that the overall impedance of the circuit is purely resistive at that particular frequency. As a result, the current flowing through the circuit reaches its maximum value, which is determined entirely by the resistive elements present, and voltage across the inductive and capacitive components will be in-phase when calculated from a practical perspective, leading to a resonance condition.

Consequently, the scenario described aligns with the principles of resonance in alternating current (AC) circuits, where reactances cancel. The other statements do not accurately reflect the behavior of the circuit in this situation; therefore, they are not valid explanations.
