Ok, so using Faraday's law and Ohm's law and assuming current density J is constant throughout at time t, I got
EMF (total) = I(t)(R1 + R2)=-ωB0cosωt
and if EMF1 + EMF2 = EMF(Total)
I(t) = (E1 + E2)/(R1 + R2)
Is that right or am I just making the same mistakes?
I've attached a screenshot of the question, and I have to admit I'm really struggling. I don't know if anyone will be able to help as optics is very diagram-dependent, but perhaps you can give me a hint without needing to draw anything.
I'm stuck on (ii) a)
The first thing I did was use...
That the sum of the voltages should be equal to zero? Sorry, I realize I'm being stupid, I just really don't know where I'm going with this. Wouldn't that imply EMF1=-EMF2?
using Faraday's law, but this is where I got stuck. Do I treat each loop separately? Do I work out the EMF in loop 1 and then loop 2? I'm guessing there is self interaction going on here (well that's what induction is), but I don't know how to set up the equation. If I take the larger loop I can...
