Parallel Resonance and Parallel RLC Resonant Circuit
At resonance there will be a large circulating current between the inductor and the capacitor due to the energy of the oscillations, then parallel circuits produce current resonance. A parallel resonant circuit stores the circuit energy in the magnetic field of the inductor and the electric field of the capacitor.

energy stored by the inductor increases only while the current is building up to its steady-state value. When the current remains constant, the energy stored in the magnetic field is also constant. If we connect an ideal inductor to a voltage source having no internal resistance, the voltage across the inductance must remain equal to the applied voltage.
