An Oscillating LC Circuit Has a Resonant Frequency of 1

Question 42

Multiple Choice

An oscillating LC circuit has a resonant frequency of 1.2 × 106 Hz. The diagram shows the system at t = 0 s when there is no charge on the capacitor and the current is in the direction shown. At this time, the energy stored in the inductor is 2.5 × 10-7 J. An oscillating LC circuit has a resonant frequency of 1.2 × 10<sup>6 </sup>Hz. The diagram shows the system at t = 0 s when there is no charge on the capacitor and the current is in the direction shown. At this time, the energy stored in the inductor is 2.5 × 10<sup>-</sup><sup>7 </sup>J.   -Determine the value of the current at the instant shown in the drawing.
