At absolute zero temperatures ..... Materials become superconductive..... Electricity pass through them without any resistance ..... According to 'V=IR' , R becomes zero ,then if resistance becomes zero do u think that any kind of potential difference exists???? And if not ...how can electrons travel through a conductor??? at such weird temperatures? |
