Hello,

I am studying transformers now for the exam and I came across this question. It made a confusion in my mind. I took the photo of the question and put it into attachment.

The answers B and C looks very similar to each other and in my humble opinion both of them are true. I would be very happy if somebody explains which is true and why.

Thank you very much.

Salih

B is true. And the longer the wire is the bigger the resistance will be.
 
Thank you, I understand now, the current must be the same everywhere. I thought in the first that because the current is being used in the long leeds, it is decreasing. But I understand that this is a misconception.
