Georg Ohm
Formulated Ohm's Law, which states the relationship between voltage, current, and resistance in an electrical circuit.

"The further the spiritual evolution of mankind advances, the more certain it seems to me that the path to genuine religiosity does not lie through the fear of life, and the fear of death, and blind faith, but through striving after rational knowledge."

"Some gentlemen of science seem to believe that the only way to understand electricity is to be shocked by it. I prefer a more theoretical approach, less electrifying, perhaps, but certainly less hair-raising."

"My law is like a good joke: simple, elegant, and once you hear it, you wonder why you didn't think of it yourself. And then you try to explain it to someone who doesn't get it, and it's no longer funny."

All quotes by Georg Ohm (358)
The magnitude of the current in a voltaic circuit is directly proportional to the electromotive force and inversely proportional to the resistance of the circuit.
A clear and distinct idea of the nature of the electric current is indispensable for the understanding of its effects.
The resistance of a conductor is directly proportional to its length and inversely proportional to its cross-sectional area.
The resistance of a conductor depends on its material and its temperature.
The electromotive force is the cause of the current.
The current is the effect of the electromotive force.
The mathematical treatment of the galvanic circuit is essential for its complete understanding.
Without mathematics, the laws of electricity would remain obscure.
The simplicity of the law of the galvanic circuit is striking.
The resistance of a circuit is the sum of the resistances of its individual parts.
The potential difference across a resistor is proportional to the current flowing through it.
The current in a circuit is determined by the ratio of the electromotive force to the total resistance.
The theory of the galvanic circuit is founded on a few simple principles.
Experiment and theory must go hand in hand.
The laws of electricity are as exact as those of mechanics.
The resistance of a conductor is a measure of its opposition to the flow of electric current.
The electromotive force is the driving power of the electric current.
The current is the flow of electric charge.
The laws of the galvanic circuit are universally applicable.
The mathematical formulation brings clarity and precision.
