At the time when the switch opens again, t = 1 s, the capacitor voltage can be found to be vC (t = 1 s) = 493 V When the switch opens again, the capacitor will discharge through the load resistor, RL ; this discharge is described by the natural response of the circuit consisting of C and RL and is governed by the following values: vC (t = 1 s) = 493 V, off = RL C = 15 s We can directly write the natural solution as follows: vC (t) = vC (t = 1 10 6 ) e (t 1 10 = 493 e (t 1 10 Print Code 39 Full ASCII In None Using Barcode drawer for Software Control to generate, create Code39 image in Software applications.

Comments Note that the voltage response shown in Figure 531 rapidly
reaches the desired value, near 5 volts, thanks to the very short charging time constant, on On the other hand, the discharging time constant, off , is signi cantly slower As the length of the cable is increased, however, on will increase, to the point that the voltage pulse may not rise suf ciently close to the desired 5V value in the desired time While the numbers used in this example are somewhat unrealistic, you should remember that cable length limitations may exist in some applications because of the cable intrinsic capacitance and resistance Focus on ComputerAided Tools The Matlab m le containing the numerical analysis and plotting commands for this example may be found in the CD that accompanies this book An EWB solution is also enclosed Check Your Understanding

TRANSIENT RESPONSE OF SECONDORDER CIRCUITS
In many practical applications, understanding the behavior of rst and secondorder systems is often all that is needed to describe the response of a physical system 5
Transient Analysis
to external excitation In this section, we discuss the solution of the secondorder differential equations that characterize secondorder circuits Deriving the Differential Equations for SecondOrder Circuits A simple way of introducing secondorder circuits consists of replacing the box labeled Circuit containing RL/RC combinations in Figure 53 with a combination of two energystorage elements, as shown in Figure 539 Note that two different cases are considered, depending on whether the energystorage elements are connected in series or in parallel Consider the parallel case rst, which has been redrawn in Figure 540 for clarity Practice and experience will eventually suggest the best method for writing the circuit equations At this point, the most sensible procedure consists of applying the basic circuit laws to the circuit of Figure 540 Start with KVL around the lefthand loop: vT (t) RT iS (t) vC (t) = 0 Then apply KCL to the top node, to obtain
