Title Text:Current (water) running through the water (wires) causes it to boil, increasing the pressure (voltage), but resisting (impeding) the flow of hydroelectricity (water currents). This is the basis for Ohm’s law. Origin:https://xkcd.com/2571/ https://www.explainxkcd.com/wiki/index.php/2571:_Hydraulic_Analogy 水力学的类比 电流(水)流经水(电线)使其沸腾，由此水压(电压)增加，但液体电(水流)的流通受阻。这就是欧姆定律的基础。 ht… Read more
