why at critical temperature in superconductors resistance becomes zero?Solution) For conductors as the temperature increases their rasistance increases and as temperature decreases the resistance decreases. If we continously decrease the temperature then a stage comes that the resistance of conductor becomes zero. The corresponding temperature is known as critical temperature. So at critical temperature the resistance becomes zero.
