Question B-005-010-010

What property allows an RF choke coil to have little effect on signals meant to flow through the coil?

Correct Answer

Low reactance at low frequencies

Explanation

At low frequencies (like DC or audio), the choke's inductive reactance (XL = 2 * π * f * L) is very low, allowing those desired signals to pass easily.
