Formal definition in an Electromagnetic course tells us that it is "It is the amount of work done in bringing a unit positive charge from infinity to that point".(definition of potential,voltage is potential difference) So it is basically work , and it is particular form of work i.e of a unit charge carrying work. Well the problem with this is we encounter the notion of infinity here. So infinity is bit paradox in nature. Lets try to get idea of infinity by some metaphor. Lets assume you are ant , but a scientific research ant and ant community is as good as human community. All facilities are to the scale of ant community.The ant present in a garden and mapping of garden and discovering many things and phenomenon in garden is work of generations for ant.
