1. The problem statement, all variables and given/known data
123984[/ATTACH]"]

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, $$\phi = 15.63^{o}$$ when the switch is open. Then you can use $$V = V_{source}\frac{Z_{R}}{Z_{total}}$$
I'm not 100% that this is the way to do it though.
