Practical importance of inductance

  1. May 10, 2008 #1
    wts the practical importance of inductance in dc and ac working?

    application of ideal current and voltage sources(dint know dey had specific applications till the time i saw dis question in a college paper....i thought dey were just theoretical....)?

    how does an ammeter measure the rms value of current?.....

    plz help me....i have my exam in 2 days.....
