I have the answer to this. It's not a homework problem. Just attempting to study. Isn't going so well. You'd think after 10+ hours of it, I'd be able to solve the 'easy' level problems in the book.
[tex]\phi = \int \vec B \cdot d \vec a[/tex]
[tex]E= -\frac{d\phi}{dt}[/tex]
[tex]E=\frac{i}{R}[/tex]
I know that at t=0, E=iR, E=(5A)(4Ohm)=20V.
I don't know even how to start this problem.
