Current Through an Oscillating LC Circuit

Click For Summary
SUMMARY

The discussion focuses on calculating the maximum current through an oscillating LC circuit with a 7.5 nF capacitor and a 4.4 mH inductor, which has a maximum voltage of 2.0 V. The maximum charge is determined to be 1.5 x 10^-8 C. The relationship between energy stored in the inductor and capacitor is established using the formula ½L I_m² = ½C U_m², confirming the ability to equate these energies during oscillation.

An oscillating LC circuit consisting of a 7.5 nF capacitor and a 4.4 mH coil has a maximum voltage of 2.0 V. What is the maximum current through the circuit?

I got 1.5x10^-8 C for the max. charge.

Got it. Forgot about the ability to set those equal to each other in oscillation.

Thanks!
