Does Current Depend on Wire Diameter?

[Bogus_Roads]

Homework Statement

Asking for drift speed, current in the second 2 mm diameter wire.

Homework Equations

electron flow=qvA, I=V/R, R depends on A---why doesn't current then depend on A?

The Attempt at a Solution

I can only solve it if the currents in both disks are the same, but doesn't current depend on A?

Think of the electrical current in the same way as water in a garden hose. If the hose gets smaller does the amount of water going through vary? What would happen if I made the hose get smaller?

So then you're saying it wouldn't be the same in the 1mm wire as in the 2 mm wire?
