These are all genuine sentences and paragraphs that were written by students in their write-ups for the 2nd year practical on High Temperature Superconductivity. Remember that all spelling mistakes, grammatical errors, and errors of logic are all entirely theirs, and have been reproduced exactly as they appeared on the student's script.
Electrons dumping in superconductors allows a current to flow without resistance.
The Cu atoms are aligned in a line. Toaster ovens, for example, are specifically designed to have a lot of resistance. If there was no resistance in a toaster, your bread would never become toast. Superconductors should not be used in toasters as they have no resistance. This can take the normal coppers electron to become a normal copper, and turn the origional copper back into copper.
