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
