1. The problem statement, all variables and given/known data

I did not understand one thing.. If it is given that a wire has a current 'i', then why do we say (in applications of laws such as biot savart law) that the current in a small element of the wire is also 'i', that is the same current that passes through the whole conductor.

2. Relevant equations

can someone explain this. i got really confused on this one.

3. The attempt at a solution

I thought we should take curent in the ' dl ' element of the wire as ' di ' and not i. I am wrong. Please Explain, anyone!
