Unformatted text preview: Capacitor has an electric eld created by the charge built up on the top/bottom plates (equal/opposite) The voltage drop is proportional to the charge: V = q/C Sum of the voltages must be 0 (Kirchoff, Germany 1845): L q + q/C = 0 The solution of q + 2 q = 0 is well known to us, but in this case = 1 / LC Total energy: 1 2 LI 2 + 1 2 q 2 /C where the rst term is magnetic inertia (kinetic) and the second term is electric potential (springlike) Mass/Spring LC circuit x q F V m L s 1/C 5. Other systems a) Pendulum: ml + mg = 0 and = p g/l b) Torsion Oscillator: I + c = 0 and = p c/I e) Water Utube: l x + 2 gx = 0 and = p 2 g/l g) Bobber in uid Torsion: m x + Agx = 0 and = p AG/m d) Mass on a tensioned string: m x + 2 Tx/l = 0 and = p 2 T/lm...
