C) its Q is zero
D) its Q is infinite

Question

Quizplus · Accepted Answer

The Q factor, or quality factor, of a coil is a measure of its efficiency, defined as the ratio of its inductive reactance to its resistance at a given frequency. A low internal resistance in a coil means it has a higher Q factor because the inductive reactance is much larger in comparison to the resistance, indicating high efficiency and selectivity.
