Question

You can increase the resonant frequency of a series-tuned RLC circuit by

Answer 1

you need to increase l.

Answer 2

decreasing the inductance or capacitance or both

Step-by-step explanation:

The frequency of a resonant LC circuit is inversely proportional to the square root of the product of L and C. Thus increasing the resonant frequency requires decreasing the product of L and C. This can be done by decreasing L, decreasing C, or both.
