Why do they say uniform conductor?

Many thanks!

Because a non-uniform conductor would significantly complicate things.

Thanks for your reply @Orodruin !

What's a non-uniform conductor? The textbook does not seem to define these 'uniform' or 'non-uniform' conductors.

Am I correct to say that a uniform conductor is cylindrical, while a non-uniform conductor can have any geometry as long as it is open at both ends.

Many thanks,
Callum

Thanks for your reply @Orodruin ! How would a non-uniform conductor significantly complicate thing?

Many thanks!

What's a non-uniform conductor?

One in which the conductance varies from place to place within it.
