electrical resistance


Both Can Do Work.....

a: Electrical resistance ~
b: a water wheel

What: "Its common to equate electrics with the flow of water in tubes, at least it works up to a point. Voltage can be compared to water pressure, current compared to the flow rate. An electrical resistance is like a water wheel, it restricts the flow of the electricity but it does work, usually producing heat. In a resistive circuit current and voltage are in phase, that is to say more water pressure leads to an increased flow rate leads to the water wheel going round faster and more work is done. Of course, in an AC circuit the water rushes backwards and forwards and the wheel changes direction with the water flow but the analogy is still sound."
