Prob 21.14- eet114 test 3e1 prob 1-9 parallel resonance

00:22:02

Parallel Resonance current at 42.86kHz.
Notice that the current thru the inductor and current thru the capacitor are almost in perfect resonance.  They feed off of each other and are 180° our of sync.  Also notice there is almost zero current flowing from the source because the two branch currents almost perfectly cancel each other out.  If the resonance was perfect, there should be zero current coming from the source.  It is not perfect because we cannot tune frequency to 2 decimal places, and the inductance and capacitance values also needed to be rounded off.
