Problem

Which one of the following expressions gives the ordinary resonant frequency

f_0

of a lossless series

LC

circuit in terms of inductance

L

and capacitance

C

? a)

f_0 = \dfrac{1}{\sqrt{LC}}

f_0 = \dfrac{1}{\sqrt{2\pi LC}}

f_0 = \dfrac{1}{2\pi\sqrt{LC}}

f_0 = \dfrac{1}{\pi\sqrt{LC}}
