Resistance is directly proportional to the resistivity and length of the conductor, and inversely-proportional to its cross-sectional area. As resistivity is affected by temperature, we can say that temperature indirectly affects resistance.
Nothing. Resistivity is a physical characteristic of a material. It's not affected by its shape, etc.
gunn diode is transfered electron device & PIN diode is semiconductor device
whether we know that p-n diode is real diode. But still in case of semeconductor we see then silics is real diode.
resistivity and resistance are two diff. things...........resistance depends on length and thickness resisitivity too depends on the area and length resistivity=resistance*area/length
