L-C Oscillations

Question|L - C Oscillation

In L-C oscillation, maximum charge on capacitor can be Q. If at any instant, electric energy and magnetic enegy associated with circuit is equal, then charge on capacitor at the anstant is

In an L-C oscillation maximum charge on capacitor can be Q_0 . If at any instant electrical energy is the 3/4 of the magnetic energy then the charge on capacitor at that instant is

The inductor in a L-C oscillation has a maximum potential difference of 16V and maximum energy of 640 mu J . Find the value of capacitor in muF in L-C circuit.

Consider a L-C oscillation circuit. Circuit elements has zero resistance. Initially at t=0 all the energy is stored in the form of electric field and plate-1 is having positive charge: at time t=t_(1) plate-2 attains half of the maximum=ve change for the first time. Value of t_(1) is :

A capacitor of capacitance 1 mu F is charged to a potential of 20 volt. The battery is then disconnected and a pure inductive coil of inductance 10 mH is connected across the capacitor so that L-C oscillation are set-up in the circuit. What is the maximum current in the circuit?
