What is inductive reactance?

• A. The measure of resistance in a circuit
• B. The opposition an inductor presents to AC flow due to inductance
• C. A form of energy storage
• D. The amount of power consumed in an AC circuit

Answer: (B)

Inductive reactance is defined as the opposition that an inductor presents to alternating current (AC) flow due to its inductance. When AC passes through an inductor, it creates a magnetic field that stores energy temporarily. As the AC current changes direction, the magnetic field collapses and induces a voltage that opposes the change in current. This phenomenon results in inductive reactance, which is directly proportional to the frequency of the AC signal and the inductance value (measured in henries) of the inductor. In practical terms, inductive reactance is significant because it affects how efficiently current can flow through the circuit. High inductive reactance can limit the current and introduce phase shifts between voltage and current, impacting the system's performance. Understanding inductive reactance is crucial for engineers and technicians working in HVAC systems, as they often deal with AC circuits and components such as motors, transformers, and solenoids that utilize inductors. Resistance refers specifically to the opposition to current flow in a circuit but does not include the frequency-related effects seen in AC circuits. Energy storage simply describes a function of inductors but does not encapsulate the concept of reactance. Power consumption pertains to the actual energy used by a circuit,
