Second-Order Circuits

Integrating two fundamental energy storage elements in electrical circuits results in second-order circuits, encompassing RLC circuits and circuits with dual capacitors or inductors (RC and RL circuits). Second-order circuits are identified by second-order differential equations that link input and output signals.

An electrical circuit comprising two irreducible energy storage elements is called a second-order circuit.

Some examples include RLC circuits as well as RC and RL circuits with dual capacitors, and inductors, respectively.

These circuits are characterized by a second-order differential equation that corre...
