Electrical Resonance

1.1 Qualitative Description of LC Resonance. At time t = 0, the voltage across the charged capacitor is at its maximum (v(max )), its associated electric field and stored energy are also at maximum, and the network current is still at zero value.That is, at time t = 0, the inductor is still "seen" by the capacitor charge as an ideal wire.
