doesn't make sense 2 me....things r diff at the microscopic level...if energy increases...then the collisions between electrons increases..thereby increasing d resistance...nd decreasing the conductance!!

sister when u increase temprature of a semii conductor the electrons become exciting and they leave there orbits and with every electron 1 hole and 1 free electron is created this increases the conductivity
if u increase the temprature too much then the vibration starts which decreses the conductance

Heat "excites" the molecules thus making the flow of electricity easier. A poor example would be this: when your very cold, it feels like your blood flow is slowed down, yet, if you are warm, your blood seems to flow faster. Does that make sense?

Because of energy
