Homework Statement
We have:
I=nAve
Imagine a copper wire with a constant current through it:
I=constant
e=constant
n (for copper)=constant
Hence, we obtain:
A is inversely proportional to electron drift velocity.
My question is: how does that make sense? Why would the cross sectional area increasing lead to the electron drift velocity decreasing?
Thanks
