Question

The battery has a voltage V = 6 V, the inductance of the inductor L = 12 mH and the capacitance of the capacitor C = 8 F. Assume that the inductor and the wires have zero resistance.

The switch S was at position a for a long time when it is switched to b. Describe the current flow in the right loop.

 

 A   There is no current flow in the loop since it is disconnected from the battery.  B   At the instant the switch is at b, the current starts to flow and then decays exponentially.  C   The current flows in a sinusoidal function with frequency . D   none of the above

Explanation / Answer

C The current flows in a sinusoidal function with a frequency .Because the energy stored in the capacitor prior to the changing of switch starts exchanging between L and C and thus it continuously oscillate.
