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 current strength is determined by the entire circuit, not by any single part alone.
The resistance of a wire of the same material varies inversely as its cross-sectional area.
Ohm's law is not merely an empirical finding; it can be derived from fundamental assumptions about the nature of electricity.
The propagation of electricity is not instantaneous, although it is extremely rapid.
The unit of resistance should be named after the discoverer of this fundamental law.
Every new theory must expect opposition.
The true method of scientific investigation is to proceed from the simple to the complex.
The mathematical treatment of physical phenomena is the key to understanding their essence.
I have sought to express the laws of the galvanic circuit in the most general and comprehensive form.
The conductivity of a material is a specific property, like its density or specific heat.
In a parallel circuit, the total conductance is the sum of the individual conductances.
The work done by the current in a conductor is proportional to the square of the current, the resistance, and the time.
The heat produced in a wire by an electric current is proportional to the square of the current and the resistance.
A circuit is a closed path through which electricity can flow continuously.
The tension of a galvanic cell depends on the materials of its electrodes and the electrolyte, not on its size.
The internal arrangement of a source of electricity affects its ability to produce a current in an external circuit.
The study of electricity requires both careful experiment and rigorous mathematics.
The laws which I have discovered will, I hope, form a solid foundation for the future development of electrical science.
