"WebJul 26, 2024 · Resistivity is a bulk property of material. Since the geometry of each resistor is different, it is quite likely that the resistivity of the material the resistors are made of differ between the resistors. The resistance, however, is the same (within tolerance, looks like 5%) between each of the resistors. " - Difference between resistor and resistivity

http://hyperphysics.phy-astr.gsu.edu/hbase/electric/resis.html WebFrom the formula v = I e n A, we can conclude that overall drift velocity in circuit decreases by using a larger resistor (as it reduces the current). Having constant current density J, electrical field in wire is E w = J ρ w and resistor E r = J ρ r. As ρ w < ρ r, it says that electrical inside resistor is stronger than in wire.
