Homework Help: Conductance physics homework

  1. Nov 14, 2008 #1
    1. The problem statement, all variables and given/known data
    123984[/ATTACH]"] physics.jpg


    2. Relevant equations

    H= (NI)/ (2(Pi)r)
    V=IR

    3. The attempt at a solution

    a)

    total resitance = 100ohms?
    from this would the current be 0.12A

    over 1ohm resistor: 0.12V

    not sure if this is correct even. Any help would be much appreciated.

    Re: conductance

    If I have calculated correctly, the total impedance is 104.40 ohms, [tex]\phi = 15.63^{o}[/tex] when the switch is open. Then you can use [tex]V = V_{source}\frac{Z_{R}}{Z_{total}}[/tex]
    I'm not 100% that this is the way to do it though.
