(a) In the diagram above the small semi-circle 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 2-dimensional 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 D-side. 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

in both V2 options
Answered by FLu
Thanks, hmmmm.
abdrahman mentioned that oen already above. Do you or anyone else have the other ones?
Answered by hmmmm
not this question . but done 80% of others
Answered by FLu
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.

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.
