Opposition to current flow in an AC circuit due to inductance is known as

• A. Capacitive Reactance (XC)
• B. Impedance (Z)
• C. Power Factor
• D. Inductive Reactance (XL)

Answer: (D)

The concept here is how a specific reactive element limits current in an AC circuit. When the opposition to current comes from an inductor, we call it inductive reactance. It’s the part of the total opposition (impedance) that is due to the inductor, and it varies with frequency as XL = 2πfL. This reactive component causes the current to lag the voltage. Capacitive reactance would be the opposite case, coming from a capacitor and causing current to lead voltage. Impedance is the overall opposition (combining resistance and reactance), and power factor relates to how much of that opposition is reactive versus real, i.e., the phase relationship between voltage and current.
