(a) In the diagram above the small semicircle in the wire above R_1 indicates that it is not in contact with the horizontal wire which it appears to intersect due to the 2dimensional projection. Additionally, the horizontal wire is continuous, not broken. Calculate V_1 in terms of the emf \mathcal\epsilon,R_1,R_2 (enter epsilon for \epsilon)
b)Calculate V_2 in terms of the emf \mathcal\epsilon,R_1,R_2 (enter epsilon for \epsilon)
c)Express V_1/V_2 in terms of R_1 and R_2
Now wrap that same wire not once around the circuit but 100 times before you connect it again to the Dside. Without realizing it, in doing so you have been building some kind of a transformer (we will discuss transformers later in the course).
d) Calculate V_1 in terms of the 1 loop emf \mathcal\epsilon,R_1,R_2 (enter epsilon for \epsilon).
e) Calculate V_2 in terms of the 1 loop emf \mathcal\epsilon,R_1,R_2 (enter epsilon for \epsilon).
f) Express V_1/V_2 in terms of R_1 and R_2

Please help!

Helps please!

Please help anyone!

anyone?

Any ideas guys?

problem2 2 (R_2*epsilon)/(R_1+R_2)

Thanks abdrrahim!
Anyone for the rest? 
Many thanks!
Please help! 
problem1 1 (mu_0*I_0*r)/(2*pi*R_1^2) 2 (mu_0*I_0)/(2*pi*r) 3 (mu_0*I_0)/(2*pi*r)*(1(r^2R_2^2)/(R_3^2R_2^2))
4 0 
Thanks abdrrahim. However, mu_0 and I_0 is not allowed it says. can you help please?

It does not work, please help!

It does not pass, pleas help!

It seems wrong, please help!

Other ones please!

Problem 2 answers please abdrrahim!

Sorry abdrrahim did not realise it was solution for Problem 1.
Do you have the others for Problem 2 please? 
Please help with Problem 2!

Problem 2 help please!

Anyone please?

Please Problem 2!

oh, come on ... someboady share problem 2 answers

Yes, please someone for problem 2!

Nobody for Problem 2 guys!?

Please for problem 2

Nobody for Problem 2?

V2=(R_2*epsilon)/(R_1+R_2)
in both V2 options 
Thanks, hmmmm.
abdrahman mentioned that oen already above. Do you or anyone else have the other ones? 
not this question . but done 80% of others

Thanks hmmmmm, what do you require? I need the second part of c) in problem 2 helmholtz hoils, do you have that please?
The answers for the other, you can read in my profile, if you don't have it yet.
Thanks. 
V1/V2=1+2*R_1/R_2
and V1/v2=100+101*(R_1/R_2) 
(a)((R_1*epsilon)/(R_1+R_2))+(epsilon)

(b)((R_1*epsilon)/(R_1+R_2))+(100*epsilon)

Great thank!

Many thanks hmmmm!
Have you by any chance found the second part (Helmholtz Coild)for Problem 3 c)?
I have all others but that one with tesla in square meter is very hard. 
Please Problem 3 c) second part tesla in meters!?

Please Problem 3) c) tesla in square meters!

sorry i slept so couldn't reply i missed that part too.
