Soldering is a way of joining one component to another component. Components on a printed circuit board are held in place with solder. Solder being a conductive compound lends itself very nicely in the electrical and electronic industries.
Voltage is the pressure that pushes electricity through wires (or other conductors) in the same way that water pressure pushes water through pipes.
One reason is because it resists corrosion and another reason is that it can easily be made into pipes for hot and cold water, oil, etc. However, compared to modern plastic materials, copper is much more expensive to use: its ore must first be mined, then the ore has to be smelted and refined into metal pipes, wires, etc. So nowadays, for drainpipes, plastic pipes are used instead of copper.
