Study Notes
Temperature Coefficient of Resistance
- In conducting materials, the temperature coefficient of resistance is positive, meaning an increase in temperature increases the resistance.
Conductor Energy Gap
- In conductors, there is no energy gap or a very small energy gap between the conduction band and valence band.
Metals as Conductors
- Metals work as good conductors of electricity because their atoms have a "sea of delocalized electrons" that can move freely, allowing the flow of electric current.
