    Could someone explain the fundamental differences between an inductor and a capacitor. I keep hearing that they are both store electric charge but what is there role in the circuit.

    please google them ...... surely you can do a little research :)
    and THEN if there is something you don't understand, come back and ask a specific question

    No, they don't.
    Capacitors store electric energy in an electric field. Classically this field is created between two plates which carry opposite charges. Here's some fundamental information.
    Inductors store magnetic energy in a magnetic field. Classically this field is created by an electric current through a coil. Here's some fundamental information.

    This cannot possibly be explained in a few words. It depends very much on the application. Typical uses for capacitors are:
    • filtering noise
    • smoothing Dc supply voltages
    • blocking DC
    Typical uses for inductors are:
    • filtering noise
    • blocking AC

    @Chr1s This is a self-help forum! That means we help those who help themselves. Your original post was a good question, and @Harald Kapp gave you a good response; however, too good in @davenn 's opinion (which I also happen to share). Please read again Dave's post #2 on this thread.

    Make Google your friend and first point of contact before posting a question here with such a broad range of possible answers.

    Learning electronics is not an easy task or everyone would do it. Your previous thread on how to wire up an Instructables project indicates that you are just beginning your trek down this road. It's a loooong road with lots of hills and valleys, twisty turns, and side roads to explore. Some folks are satisfied to just play "monkey see, monkey do" by putting parts together, without any understanding of what functions those parts perform, or how their circuit actually works. There is nothing wrong with that, but IMHO you do not learn much about electronics by simply building circuits someone else designed. Still, it is a hobby, and you are free to do whatever pleases you. The fact that you asked the question indicates you want to learn electronics. We will help (if we can) no matter what your skill level happens to be, but you are expected to do your part too.

    Oh, and welcome to Electronics Point!

    No problem. I understand. It feels good to be apart of a community :)
