Select the properties that apply to superconductors.

made from pure metals
conduct electricity with zero resistance
produce a strong magnetic field
no loss of energy in the transfer of electricity

made from pure metals . . . no;
they've been made from all kinds of weird compounds and alloys.
 
conduct electricity with zero resistance . . . yes;
that's why they're called "superconductors".

produce a strong magnetic field . . . possible, but not because it's a superconductor;
just like any other conductor, the magnetic field depends on the current that's flowing in the conductor.

no loss of energy in the transfer of electricity . . .
there's no loss of energy in the current flowing in the superconductor;
but if you tried to transfer the current out of the superconductor into
something else, then there would be some loss.

W0lf93. energy flows from the producer level to the consumer level.

Ithink the answer would be 1,350!
