1.10 Resistance & Resistivity Flashcards
1
Q
Resistivity
A
The resistance of 1m of material of CSA 1m2
2
Q
Superconductor
A
-A material which looses all its electrical resistivity
-to become a prefect conductor
-when it is below its critical temp
3
Q
Ohms law
A
-Potential difference across the conductor is proportional to current through it,
- provided temperature remains constant
