Superconducting materials payes attention of scientists for its important roles in generation of powerful magnetic field and electric energy beside transportation and magnetic resonance imaging (MRI).in this work potential dependent special relativity was used to define the electric resistance. The material becomes a superconductor when the electric and magnetic field compared become extremely large compared to the rest mass energy. The critical temperature was found to be directly proportional to the field potential. Strong mechanical pressure can also convert materials to a super conductors provided that it exceeds the rest mass energy in the absence of fields. The critical temperature is found to be directly proportional to the applied pressure.
Fortunately the results obtained are in agreement with the experimental works specially for high temperature supercoductors Like YBCO.
