    these buck converter questions are throwing me for a loop for some reason

    [​IMG]

    all of this is straight from the text book

    IL=Vo/R=.5

    then it states IL=Io

    so the output current is 0.5A which doesnt really help at all

    is this just a case where I need to use simple ohms law? in a RLC circuit?

    Arguing purely on energy considerations the average load power = 0.75W

    The average source power must be the same.

    Average source current=0.75W/6V=.125A

    wow thats easy. I was over thinking this

    why must my textbook make something simple, sound so complicated?
