Once there was copper, there came copper wires.
And copper wire is a very good conductor.
If he could find magnetite, then he would have the capacity to produce low-power electric motors and generators.
He wouldn't produce batteries, as he had forgotten the principles behind them.
As for how to make the insulation paint on the outside of copper wires, he did not know.
He can only think of a method in the future.
He tried to pull copper bars through small holes in steel, and then copper wire was drawn out.
Easily obtained ten meters of copper wire, just like what he had seen at home.
Very suitable for making conductors, but now he neither knew how to produce batteries nor had magnets to make generators and motors.
Perhaps he needs to further explore this world to find these resources.
Regarding the issue of currency.
Currently, there is only copper and tin, no gold or silver.
