the RC and RL circuits are of the first order. • Hence, the circuits are known as first-order circuits. • Two ways to excite the first-order circuit: (i) source-free circuit The energy is initially stored in the capacitive of inductive elements. The energy couses the current to flow in the circuit and gradually dissipated in the resistors.
In the circuit of Figure 9.5.6, it should be obvious that the larger the resistance value, the larger the resulting initial-state voltage. From Equation 9.2.9 it can be seen that if the voltage across the inductor is increased, then the initial rate of change of current with respect to time will increase, and that implies a shorter time constant. For more complex circuits, Thévenin''s theorem ...

The so-called energy storage means that when the circuit breaker is de-energized (that is, when it is opened), it opens quickly due to the spring force of the energy storage switch. Of course, the faster the circuit breaker is opened, the better. This is to have enough power to separate the contacts when the segmentation fault has a large current (excessive current will melt the …
