Week 13: Second Order Circuits | Source Free Series RLC Circuit

In the previous lesson, we considered circuits with a single storage element(a capacitor or an inductor). Such circuits are first-order because the differential equations describing them are first-order. In this lesson, we will consider circuits containing two storage elements. These are known as second-order circuits because their responses are described by differential equations that contain second derivatives. We will consider circuits that are excited by the initial conditions of the storage elements. Although these circuits may contain dependent sources, they are free of independent sources. These source-free circuits will give natural responses as expected.
