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)
A perfect conductor would have a resistance of zero.
The galvanic current is a constant stream of electric matter.
The communication of electricity from one body to another depends on the conductivity of the medium between them.
I have found that the conducting power of wires of different lengths and thicknesses... can be represented by a simple formula.
The action of the galvanic apparatus depends essentially on the resistance which the conductor offers to the passage of electricity.
The magnetic effect of the current is proportional to the intensity of the current.
Nature seems to have chosen the simplest laws for the operation of the galvanic circuit.
The opposition which a conductor presents to the passage of electricity I call its resistance.
The sum of the tensions in a closed circuit is equal to the sum of the products of current and resistance in each part.
If the conductor is homogeneous and of uniform cross-section, the resistance is proportional to its length.
The current is the same in every part of a simple, unbranched circuit.
The electromotive force acting between the extremities of any part of a circuit is the product of the strength of the current and the resistance of that part.
My greatest wish is that this work may contribute to the advancement of physics.
The resistance of a conductor increases with its temperature.
The conducting power of metals for electricity is vastly superior to that of liquids.
The force which maintains the current is not in the conductor, but in the apparatus which produces the tension.
In a series circuit, the total resistance is the sum of the individual resistances.
The flow of electricity is analogous to the flow of heat.
A source of electricity has an internal resistance.
The potential difference is the driving force for the electric current.
