### Circuit Oscillation

- If a charged oscillator is connected to an inductor, charge begins to flow in the circuit. As time goes by, charge decreases on the capacitor while the current increases; hence the electric energy stored in the capacitor decreases while the magnetic energy stored in the inductor increases. Eventually, all the electric energy is transferred to the magnetic energy. As time goes by, the magnetic energy is lost in favor of the electric energy, and so on so forth. What we end up with is circuit oscillations whereby energy is continually converted form electric to magnetic and vice versa.
- The circuit oscillations are similar to the oscillations in a spring-block system where energy is continually converted from elastic energy to kinetic energy and vice versa.
- The angular frequency of the LC circuit oscillations is w = ( 1 / LC )^1/2.
