WebJan 11, 2016 · Current step to LC circuit. An inductor is a device which adjusts its voltage to keep the same current flowing through. However, the current exponentially decays when there is no source any more. Similarly, a capacitor is a device which keeps the voltage across itself constant. However when charged, the voltage exponentially decays when a … WebAug 14, 2024 · There is only one certain rule for finding Lagrangians: The Lagrangian is chosen such as to get the correct equations of motion. Never forget that. In the case of a circuit problem, the most sure way to know you got the right Lagrangian is to see if it gives you the right equations of motion, i.e. the equations you get from Kirchhoff's laws.
