B) approaches zero.
C) approaches infinity.
D) approaches one.

Quizplus · Accepted Answer

The inductive reactance (XL) of a coil is given by the formula XL = 2πfL, where f is the frequency of the AC voltage and L is the inductance of the coil. As the frequency (f) approaches zero, the inductive reactance (XL) also approaches zero, because the product of zero with any finite value (the inductance L) is zero.
