The correct term for the opposition to the flow of current in an alternating current (AC) circuit due to inductance is inductive reactance. This specific type of reactance arises because inductors store energy in a magnetic field when current flows through them. When the AC voltage changes direction, the inductor resists that change, which results in a phase shift between the voltage and current in the circuit.

Inductive reactance is quantified by the formula (X_L = 2\pi f L), where (X_L) is the inductive reactance, (f) is the frequency of the AC signal, and (L) is the inductance of the coil. As the frequency increases or if the inductance increases, the inductive reactance also increases, leading to more opposition to the changing current.

In contrast, capacitive reactance, which is linked with capacitors and opposes the change in voltage, pertains to a different aspect of AC circuits. Impedance is the overall opposition to current in an AC circuit, which includes both resistance and reactance (inductive and capacitive), but does not specifically focus solely on inductive effects. Conductive resistance refers to the opposition to current flow in a conductor
