In a pure LC circuit, what is the energy stored when peak current is `I_(0)`?

What is the energy stored in a pure LC circuit ?

An LC circuit contains a 20 mH inductor and a 50 muF capacitor with an initial charge of 10 mС. The resistance of the circuit is negligible. Let the instant the circuit is closed be t = 0. a. What is the total energy stored initially? Is it conserved during LC oscillations? b. What is the natural frequency of the circuit? c. At what time is the energy stored i. completely electrical (i.e., stored in the capacitor) ii. completely magnetic (i.e., stored in the inductor) d. If a resistor is inserted in the circuit, how much energy is eventually dissipated as heat?

A 1.5 mH inductor in LC circuit stores a maximum energy of 17 mu J. What is the peak current ?

An LC circuit contains a 20 mH inductor and a 50 muF capacitor with an initial charge of 10 mC. The resistance of the circuit is negligible. Let the instant the circuit is closed be t = 0. (a) What is the total energy stored initially? Is it conserved during LC oscillations? (b) What is the natural frequency of the circuit? (c) At what time is the energy stored (i) completely electrical (i.e., stored in the capacitor)? (ii) completely magnetic (i.e., stored in the inductor)? (d) At what times is the total energy shared equally between the inductor and the capacitor? (e) If a resistor is inserted in the circuit, how much energy is eventually dissipated as heat?
