Find the conservation of electrical energy in the LCR

Click For Summary
SUMMARY

The discussion focuses on the conservation of electrical energy in an LCR circuit, specifically analyzing the equations LdQ²/dt + Q/C = 0 and LdQ²/dt + RdQ/dt + Q/C = 0. Participants highlight the need for a circuit diagram to clarify which LCR configuration is being referenced. Additionally, there is a request for verification of the derivative notation used in the equations, emphasizing the importance of accurate mathematical representation in solving the problem.

PREREQUISITES

Which LCR? there's no diagram!

Also, derivate notation involves the same power on top as the bottom, i.e d^2Q/dt^2, so can you double check your listed relevant equations.
