La ley de ohm establece que la intensidad eléctrica que
circula entre dos puntos de un circuito eléctrico
es directamente proporcional a la tensión eléctrica entre dos dichos puntos.
En enero de 1781, antes del trabajo de Georg Ohm, Henry
Cavendish experimentó con botellas
de Leyden y tubos de vidrio de diferente diámetro y longitud llenados
con una solución salina. Como no contaba con los instrumentos adecuados,
Cavendish calculaba la corriente de forma directa: se sometía a ella y
calculaba su intensidad por el dolor. Cavendish escribió que la
"velocidad" (corriente) variaba directamente por el "grado de
electrificación" (tensión). Él no publicó sus resultados a otros
científicos a tiempo, y sus resultados fueron desconocidas hasta que Maxwell los
publicó en 1879.
En 1825 y 1826, Ohm hizo su trabajo sobre las resistencias,
y publicó sus resultados en 1827 en el libro Die galvanische Kette,
mathematisch bearbeitet (Trabajos matemáticos sobre los circuitos eléctricos). Su inspiración la obtuvo
del trabajo de la explicación teórica de Fourier sobre
la conducción del calor.
What does the law of ohm.
Ohm's law states that the electrical current flowing between two points in an electrical circuit is directly proportional to the voltage between two such points.
In January 1781, before the work of Georg Ohm, Henry Cavendish experimented withLeyden jars and glass tubes of different diameter and length filled with a saline solution.As it did not have the right tools, Cavendish estimated current directly: he submitted to it and estimated its intensity by pain. Cavendish wrote that the "speed" (current) varieddirectly by the "degree of electrification" (voltage). He did not publish his results to other scientists on time, and the results were unknown until Maxwell published them in 1879.
In 1825 and 1826, Ohm did his work on resistance, and published his results in 1827 in the book Die Kette galvanische, Mathematisch bearbeitet (mathematical work onelectrical circuits). His inspiration was the work of the theoretical explanation on theFourier heat conduction.
