I'm not an electrician, but drawing an analogy to water you can think of voltage as water pressure in the sense that you can have a small stream of high pressure water as in a water pik or a large current of low pressure water as a river. The river carries more energy despite having a lower voltage.
- midoridensha 4y agoExactly: this is the normal analogy used for understanding voltage and current. In a pipe with water, you could have a gargantuan pipe carrying water from a lake or river, at very low pressure (only gravity is moving it), but with a gigantic volume, so the total energy is huge. Or you could have a tiny pipe in your house with water at high pressure (60-90 psi is normal for municipal water supplies), but the total amount of water is low, so the total energy is low compared to that huge pipe with river water.
- osigurdson 4y agoThe analogy breaks down once you reach sonic flow in the pipe however.
