Parallel RLC Natural Response Example & Intuition

What should the signal shape of parallel underdamped RLC natural response voltage look like? Does more damping in parallel RLC increase or decrease damping? How can we answer this question by looking at the characteristic roots equations? This video explores these questions and related technical intuition in a specific example parallel RLC circuit example with initial condition inductor current. This video complements the Parallel RLC Underdamped Natural Response Derivation video. RLC Natural response derivations, for both series and parallel RLC, including the damping cases overdamped, critically damped, and underdamped, covered in this book: “First and Second Order Circuits and Equations – Technical Background and Insights, which is available from John Wiley & Sons ISBN: 978-1-119-91353-5 https://www.wiley.com/en-us/First+and... This video references specific equation numbers from chapter 14 of this book. This video complements the Parallel RLC Underdamped Natural Response Derivation video.
