applied K. determined L. frequently We now consider those RLC circuits in which DC sources are 1 into the network and produce forced 2 that do not necessarily vanish as time becomes infinite. The general solution is obtained by the same 3 that was followed in RL and RC circuits: the forced response is 4 completely; the natural response is obtained as a suitable 5 form containing the appropriate number of 6 constants; the 7 response is written as the sum of the forced and the natural responses; and the 8 conditions are then determined and 9 to the complete response to find the values of the constants. It is this last step which is quite 10 the most troublesome to students.
