all what I know that when a material be cooled to the critical temperature its changes to super conductive material and this mean no resistance so when we put voltage source for a short time there's a current move for un certain time &this property happens because there's no collision between...
what happen to the conductor if it reaches the critical temperature where high conductivity and then back to the original case does it preserve by an amount of high conductivity or high conductivity disappear
just a question I'm engineering student electrical power department
