Document Summary

Two types of 1st order circuits: rc and rl. Solve for the voltage across the capacitor with respect to time. t=0 v s. Perform kvl and solve for the inductor current. The solution to this general form can be written: is the where : t. We can de: the "ini, the " fin termine tial l a and the t time constan. A and determined by the source mag nitude. through two conditions: The equations are . and and y the final response we can use to determine y( 0 we can easily see that h and. A therefor e y( ) t y y( y( The time constant for the two different types of networks are: It should be noted that it may be necessary to thevenize a circuit to determine what these values are. Case 1 rc network - charge phase - voltage. C v s t e determined earlier t.
