LC circuits

LC circuit diagram

The second order differential equation governing the current i(t) in the LC circuit is

\frac{d ^{2}i(t)}{dt^{2}} + \frac{1}{LC} i(t) = 0.\,

Thus, the complete solution to the differential equation is

i(t) = Ae ^{+j \omega t} + Be ^{-j \omega t}\,

The resonant frequency of the LC circuit is

\omega = \sqrt{1 \over LC}
