Homework Help: Self induction

  1. Jul 12, 2010 #1
    A 50.0mh inductor is connected to an ac voltage source of 24.0V.The current flowing in this circuit is 0.60A.The frequency of the voltage source is :
    a)50Hz
    b)60Hz
    c)1.27*10^3 Hz

    My Work so far ! :
    f = w/2pi.

    But here we have L , E and i.

    Any help will be welcomed.

    You can do better than this. How will you bring in L, E and i? Think impedance.

    So,impedance is : z=Lw = L*2pi*f ....

    A guess , z = V/I = E/i !! but V(max)/I(max)

    If z = V/I, can you relate ω to V and I?

    So is it , V/I=Lw then V/LI=w=2pi*f .
