Zero inital conditions

  1. Oct 10, 2008 #1
    Hi all,
    a quick question, if we assume zero inital condtions does that mean that we replace each voltage source by a short circuit and a current source with an open circuit??

    ???? What has "zero initial conditions" mean? Does it mean that we assume at t=0, everything is 0? If so, then what has that got to do with zeroing all the current and voltage sources? That method you described is part of finding equivalent Thevenin resistance. You have to be more explicit.

    Zero initial conditions means that the currents in all inductors and the voltages in all capacitors are zero at t=0 , so the dynamics of the circuit is a function of the power sources. Of course they cannot be zeroed.
