Question B-005-010-007

What property allows a coil wound on a ferrite core to mitigate the effects of an offending radio signal?

Correct Answer

High reactance at radio frequencies

Explanation

An RF choke (coil, often on ferrite) presents a high inductive reactance (XL) to RF signals, blocking their passage along a wire, while allowing lower frequencies (like DC or audio) to pass.
