Super conductors would have zero resistivity. Hence no loss due to joule's heating. So power transmission could be done with larger efficiency.
Strong electric current could be passed without hesitation due to zero resistance. Hence intense magnetic field could be produced. With this levitation of trains above the rails and hence fast movement of trains.
With magnetic propulsion technique satellites could be launched without using rockets.
In computers for storing a vast memorable information super conductors could be used.
Even generators of several mega watts but of smaller size could be designed.
All of them.
The electrical trade is one of many trades that use conductors for projects.
