An Oscillating LC Circuit Has a Resonant Frequency of 1 Δ\Delta

Question 61

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.   -Which one of the following statements is true for this circuit? A) When the current in the inductor is zero,  \Delta I/ \Delta t = 0 A/s. B) The circuit will allow dc as well as ac current to flow. C) The magnetic field in the inductor is a maximum at t = 0 s. D) The charge on the capacitor will be a maximum at t = 4.2 × 10<sup>-</sup><sup>7</sup> s. E) As the current through the inductor decreases, the induced emf in the coil is directed opposite to the direction of the current.
