What is the opposition to alternating current flow through a coil due to inductance called?

AI Explanation
The correct answer is C) inductive reactance. Inductive reactance is the opposition to alternating current (AC) flow through a coil due to inductance. Inductance is the property of a coil that opposes changes in the electric current, creating a voltage that opposes the change. This opposition to AC flow is called inductive reactance, and it is measured in ohms. The other options are incorrect because: A) Reactive inductance is not a term used to describe the opposition to AC flow. B) Impedance factor is a broader term that encompasses both resistive and reactive components, including inductive reactance. D) Capacitive reactance is the opposition to AC flow due to capacitance, not inductance.
