Solved: Show that the fraction of electromagnetic energy

Chapter , Problem 87

(choose chapter or problem)

Show that the fraction of electromagnetic energy lost(to thermal energy) per cycle in a lightly damped(R2 4L/C) LRC circuit is approximatelyA U _ 2ttR _ 1tt_U ~ La) ~ <2 The quantity Q can be defined as Q = Lco/R, and is calledthe Q-value, or quality factor, of the circuit and is a measure ofthe damping present. A high Q-value means smaller dampingand less energy input required to maintain oscillations.
