Question

Why does Bernoulli's principle seem to contradict Ohm's law? That is, with a rise of "I" (speed of fluid), "V" (pressure/potential energy) decreases.

Answer 1

Bernoulli's principle is for fluids in motion and Ohm's law is for Electric Current..
They are not related to each other any which way..
How can they contradict each other?

Answer 2

Analogies of Ohm's laws can be used in heart flow and similar cases.
If you crudely imagine current to be the flow of water then it seems (at least intuitively) an obvious analogy.

Answer 3

But that's just an 'analogy'
You can't compare the two in each aspect!

Answer 4

OK, I'll state a slightly different question: which is the difference between electrons and fluids that causes\[V \propto I\] in electrons, and \[V \propto \frac{1}{I}\]in fluids?

Answer 5

http://en.wikipedia.org/wiki/Bernoulli's_principle
'decrease in pressure or a decrease in the fluid's potential energy'
my choice of V in the fluids part, I think, was justified

Answer 6

electrons flowing does not constitute a fluid. the water analogy is just an analogy. it fails in many regards and makes sense in a few.

Answer 7

My question is WHICH regard or regards in this specific case?
