O QUE SIGNIFICA OHM'S LAW EM INGLÊS
Lei de Ohm
A lei de Ohm afirma que a corrente através de um condutor entre dois pontos é diretamente proporcional à diferença de potencial entre os dois pontos. Apresentando a constante de proporcionalidade, a resistência, chega-se à equação matemática usual que descreve essa relação: onde eu é a corrente através do condutor em unidades de amperes, V é a diferença de potencial medida através do condutor em unidades de volts e R é a resistência do condutor em unidades de ohmios. Mais especificamente, a lei de Ohm afirma que o R nesta relação é constante, independente da atualidade. A lei foi nomeada após o físico alemão Georg Ohm, que, em um tratado publicado em 1827, descreveu medidas de tensão e corrente aplicadas através de circuitos elétricos simples contendo vários comprimentos de fio. Ele apresentou uma equação um pouco mais complexa do que a anterior para explicar seus resultados experimentais. A equação acima é a forma moderna da lei de Ohm. Na física, o termo Lei de Ohm também é usado para se referir a várias generalizações da lei originalmente formuladas por Ohm.
definição de Ohm's law no dicionário inglês
A definição da lei de Ohm no dicionário é o princípio de que a corrente elétrica que passa por um condutor é diretamente proporcional à diferença de potencial através dele, desde que a temperatura permaneça constante. A constante de proporcionalidade é a resistência do condutor.
