| 1. | The hydraulic analogy is a useful way of understanding many electrical concepts.
|
| 2. | A hydraulic analogy is sometimes used to describe Ohm's law.
|
| 3. | :: Hydraulic analogies are often useful in this case.
|
| 4. | :The hydraulic analogy is always useful in these cases.
|
| 5. | :Voltage is pressure, not just in the hydraulic analogy but literally.
|
| 6. | :: I have the impression that the hydraulic analogy is misplaced here.
|
| 7. | The hydraulic analogy compares electric current flowing through circuits to water flowing through pipes.
|
| 8. | :Maybe the hydraulic analogy will help.
|
| 9. | Although analogies like the Hydraulic analogy are useful, they can break down when looked at closely.
|
| 10. | Therefore, Poiseuille's law and the hydraulic analogy are useful only within certain limits when applied to electricity.
