Iron’s melting point is 2,800 deg F. Copper’s melting point is 2,000 deg F. We didn’t develop the fuel tech needed to make high temps to melt iron ore until the early 18th century. That’s why copper and bronze (copper+tin) were widely used more often and for centuries before steel

So for example, if you have 10 ohms, 12 amps, there will be 120 volts.
V = I*R ; volts = current * resistance
OR
volts = amps * ohms 🤷🏻♀️
