Chapter 24 Transients in R—L—C systems
24.1 First- and second-order systems
There are two types of system that we shall be concerned with: first-order and second-order systems:
- A first-order system is one that can be modelled using a first-order differential equation. First-order electrical systems involve combinations of C and R or L and R.
- A second-order system is one that can be modelled using a second-order differential equation. Second-order electrical systems involve combinations of all three types of component: L, C and R.
You met the time response of simple C–R and L–R systems in the last chapter. In the first case, the voltage developed ...
