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."
— from Attributed
"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."
— from Attributed
All quotes by Georg Ohm (358)
The 'strength' of a current is not a vague concept, but a definite quantity that can be expressed numerically.
The effects of temperature on resistance are not random, but follow a predictable pattern that can be incorporated into the theory.
The internal resistance of a battery is a crucial factor that must be accounted for in circuit analysis.
The combination of resistances in series and parallel can be predicted and calculated with mathematical precision.
The resistance of a conductor is independent of the current flowing through it, within certain limits.
The 'electrical force' is not a mystical entity, but a measurable potential difference.
My work provides a foundation for the practical application of electricity, enabling engineers to design and build reliable circuits.
The resistance of a conductor is a property inherent to the material, not a consequence of the current itself.
The concept of 'electrical potential' is central to understanding the flow of current.
The reluctance of some to accept my findings is a testament to the difficulty of abandoning long-held, but ultimately flawed, beliefs.
The mathematical elegance of my law speaks to its fundamental truth.
The precise measurement of electrical quantities is not a trivial task, but it is essential for scientific progress.
My theory allows for the prediction of electrical behavior in complex circuits, not just simple ones.
The 'electrical fluid' analogy, while intuitive, ultimately hinders a deeper, quantitative understanding.
The relationship between voltage, current, and resistance is a universal law, applicable to all conductors.
The scientific community must embrace mathematical physics to advance its understanding of natural phenomena.
The resistance of a conductor is not a 'loss' but a fundamental characteristic that governs the current flow.
The quantitative relationships I have established are not arbitrary, but derived from careful experimentation and logical deduction.
The 'force' that drives electricity is not a mysterious influence, but a measurable potential difference.
My work provides a clear and unambiguous definition of electrical resistance.
