Dec 19, 2018 at 1:00 comment added user2357112 This illustrates one of the big flaws of the hydraulic analogy - now you have to understand hydraulics, too.
Dec 18, 2018 at 12:08 comment added nigel222 Head of water (Pressure) is equivalent to voltage, Quantity of water flowing to current. If you have ever watered plants using a hose connected to a water butt one day, and the mains water tap the next, you ought to have a good feel for this.

Dec 17, 2018 at 20:46 comment added David Schwartz "the more water that flows per unit of time, the more energy gets delivered to the wheel per unit of time: power = current" This reasoning is not correct. At most, that more of one means more of the other suggests that they're proportional.

Dec 17, 2018 at 10:18 comment added Aetol Pressure does matter to hydraulic power, that's why water is piped from mountain dams to valley power stations.
Dec 17, 2018 at 8:10 comment added slebetman Actually, in the case of the water wheel, power = speed of water (voltage) x current (volume of water / unit time). No, speed != volume of water/time, it is miles per hour (or m/s if you prefer).
Dec 16, 2018 at 23:16 comment added Criticize SE actions means ban In the case of a water wheel, it's the amount of water flowing times how hard the water pushes the wheel.

Dec 16, 2018 at 19:02 comment added user196418 Can you make your post a little more exact? Are you saying Power = Current? Please define all terms. And make sure units match up.
