Question B-005-010-009

What property allows an RF bypass capacitor to have little effect on an audio circuit?

Correct Answer

High reactance at low frequencies

Explanation

At audio frequencies, the capacitor's reactance (XC = 1 / (2 * π * f * C)) is very high, so it does not significantly affect the desired low-frequency audio signals.
