Question B-005-012-008

A coil and an air-spaced capacitor are arranged to form a resonant circuit. The resonant frequency will remain the same if we:

Correct Answer

add a resistor to the circuit

Explanation

Adding resistance affects the circuit's Q (quality factor) and bandwidth, but does not change the resonant frequency itself (f_res = 1 / (2 * π * sqrt(LC))).
