Superconductors and Transition Metals

Normally metals have some electrical resistance, even realy good conductors. Resistance means whenever electricity flows through, they heat up and some electrical energy wasted as heat.

If you make a metal cold enough, the resistance completely disappears and the metal becomes a superconductor. With no resistance, electrical energy turned to heat and none is wasted.

Means you can start a current flowing through superconducting circuit, take out battery and current would continue forever.

Using superconducting wires you can make power cables that transmit electricity with no loss of power (loss-free power transmission), really strong…
