>Does it increase when the pipe gets smaller to compensate?
Yes. This is because mass is conserved and also water is pretty much incompressible.
>current
Yes. This follows from conservation of charge. Basically, the net charge inside a control volume is equal to the flux into the control surface, minus the flux out (because charges dont spontaneously pop into existence). Because charges are not accumulating (we aren't playing with capacitors), we hence know that the current is the same at all points.

You're missing respective leading constants of 1/2j and 1/2 on the RHS of each of those equalities, hun
