Does the resistance of an object depend on the path current takes through it? consider, for example, a rectangular bar—is its resistance the same along its length as across its width? (see above.) above does current taking two different paths through the same object encounter different resistance?

Explanation:

An object's resistance depends on its form and the substance it is made from.  The electrical resistance R of the cylinder, as you might expect, is directly proportional to its length L, similar to a pipe's resistance to fluid flow. The longer the cylinder, the more charges of collisions with its atoms can occur. The bigger the cylinder diameter, the more current it can carry.
