Resistivity Flashcards
1
Q
Resistivity units
A
Ohms meter
Ωm
2
Q
What is Resistivity
A
Resistivity is the resistance to the flow of current from one end of a material to the other
3
Q
Difference between resistivity and resistance
A
Resistance is directly proportional to the length and temperature while it is inversely proportional to the cross-sectional area of the material and Resistivity is only proportional to the nature and temperature of the material
4
Q
How to get resistance from resistvity
A
Resistance = Resistivity x length/area
