Second order transients are typically described as one of the following: overdamped. critically damped. underdamped. undamped. The word "damped" refers how two different types of energy storage elements (capacitors and inductors) interact as energy is dissipated. The math in general shows the combination of two sinusoidals riding on two
If there is nothing in parallel with the switch branch, then the opening switch can interrupt the current only by absorbing all of the energy stored in the circuit inductance and recovering against the open circuit voltage of the current source. The severity of the switching problem depends upon the makeup of the rest of the circuit.

That is why we say that "inductors act as a short circuit to a dc current". Since there can not be infinite voltages, the current through an inductor cannot change instantaneously.(However, the voltage can.) This means that i L (t +) = i L (t - ) The energy stored in an inductor is: (w L) 0-->t = w L (t) = ½ L i 2 – ½ L i 0 2 From this we see that
1.2 First Order Circuits. First order circuits are defined as those where any voltage or current can be obtained using a first order differential equation. Some examples of first order circuits are: Circuits with a single electrical energy storage element: inductor or capacitor, Fig. 1.3.
First-order systems. Up to now we''ve looked at first-order circuits, RC ― and RL ―, that have one energy-storage element, C or L .

However, a should be equivalent definition of the order of a system is the number of independant energy storage components, of which this circuit has two. I know that the transfer function is first order, but there are two seemingly independant energy storage devices in this circuit.

Inductors are our other energy - storage element, storing energy in the magnetic field, rather than the electric field, like capacitors. In many ways, they exist as duals of each other. Magnetic field for one, electric for the other; current based behavior and voltage based behavior; short - circuit style behavior and open - circuit style behavior.

1.4: Electric Circuit Elements. Circuit elements are the basic building blocks of an electric circuit. Essentially, an electric circuit is the interconnection of these elements. Within electric circuits, one can find two types of elements: passive and active. Active elements have the ability to generate energy, whereas passive elements do not.
An inductor can be used in a buck regulator to function as an output current ripple filter and an energy conversion element. The dual functionality of the inductor can save the cost of using separate elements. But the inductor''s inductance value must be selected to perform both functions optimally.
