Homework Help: Capacitors vs. inductors

  1. Sep 26, 2010 #1
    1. The problem statement, all variables and given/known data

    Contrast capacitors and inductors.

    2. Relevant equations

    3. The attempt at a solution

    I THINK it can be said: capacitors act as a slowing device, or "inertia" to changes in voltage since they store energy in an electric field. Conversely, inductors act as a slowing device, or "inertia" to changes in current since they store energy in a magnetic field.

    Could it be said, then, that for unit resistance, so V = IR = I*1 (specially-designed system of units), that V = I, and inductors and capacitors "do the same thing", since voltage "inertia" actually "becomes" current inertia? And, for R --> infinity, do the effects of inductors go away, and the effects of capacitors become maximized? And for R --> 0, do the effects of capacitors go away, and the effects of inductors become maximized?
