Editing LC circuit (section)

== Resonance effect ==
[[Resonance]] occurs when an LC circuit is driven from an external source at an angular frequency {{math|''ω''<sub>0</sub>}} at which the inductive and capacitive [[Reactance (electronics)|reactance]]s are equal in magnitude. The frequency at which this equality holds for the particular circuit is called the resonant frequency. The [[Electrical resonance|resonant frequency]] of the LC circuit is

: <math>\omega_0 = \frac{1}{\sqrt{LC}},</math>

where {{mvar|L}} is the [[inductance]] in [[Henry (unit)|henries]], and {{mvar|C}} is the [[capacitance]] in [[farad]]s. The [[angular frequency]] {{math|''ω''<sub>0</sub>}} has units of [[radian]]s per second.

The equivalent frequency in units of [[hertz]] is

: <math>f_0 = \frac{\omega_0}{2 \pi} = \frac{1}{2 \pi \sqrt{LC}}.</math>
