In the water flow analogy sometimes used to explain electric circuits by comparing them to water-filled pipes, voltage difference is likened to water pressure difference.
The relationship between voltage and current (in ohmic devices) is defined by Ohm's Law.

Famous quotes containing the words water, flow and/or analogy:
“If water is too clear, it will not contain fish; people who are too cautious will never gain wisdom.”
—Chinese proverb.
“Logic and fact keep interfering with the easy flow of conversation.”
—Mason Cooley (b. 1927)
“The analogy between the mind and a computer fails for many reasons. The brain is constructed by principles that assure diversity and degeneracy. Unlike a computer, it has no replicative memory. It is historical and value driven. It forms categories by internal criteria and by constraints acting at many scales, not by means of a syntactically constructed program. The world with which the brain interacts is not unequivocally made up of classical categories.”
—Gerald M. Edelman (b. 1928)
