Real resistors always add noise called Johnson noise that depends only on their resistance value and temperature
A resistor can act like a very small inductor or capacitor at high frequencies because of its physical construction
Carbon composition resistors can dramatically change value with age and surge stress yet still measure fine at room temperature
SMD resistors can fail open from mechanical board flex long before their power rating is actually exceeded
Using parallel resistors not only spreads power dissipation but also reduces overall noise compared to a single part
