Answer:
ohm's law
at constant temperature potential difference between two enda of a conductor is directly propotioanl to current flows through it
V α I
V=RI
R= propotionality constant, Resistance of the conductor
ohm's law is valid only under constant temperature
ohm's law is not valid for semiconductors insulators and super conductors
conductors whivh obey ohms law is called omic conductors
