Homework Help: Electric circuits problem (RL/C circuits)

  1. Jun 12, 2005 #1
    when solving a RL or RC circuit, what's the easiest way to tell if it is a natural response problem or step response?

    What about the differential equation?

    Are you asking about the difference between natural response and forced response? That depends on the forcing function.

    See this page - http://www.absoluteastronomy.com/encyclopedia/c/ca/capacitor.htm [Broken], and

    Or perhaps you are referring to the initial conditions - Initial potential or charge on a capacitor, or initial current in an inductor, which is then discharged, as opposed to no potential or charge on capacitor, or no initial current in an inductor, which then has a potential applied at some time, to.
