Title: Lagrangian for RLC circuits using analogy with the classical mechanics concepts,
Abstract: We study and formulate the Lagrangian for the LC, RC, RL, and RLC circuits by
using the analogy concept with the mechanical problem in classical mechanics
formulations. We found that the Lagrangian for the LC and RLC circuits are
governed by two terms i. e. kinetic energy-like and potential energy-like
terms. The Lagrangian for the RC circuit is only a contribution from the
potential energy-like term and the Lagrangian for the RL circuit is only from
the kinetic energy-like term.
