O QUE SIGNIFICA POTENTIOMETER EM INGLÊS
Potenciômetro
Um potenciômetro / pɵˌtɛnʃiɒmɨtər /, informalmente um pote, é um resistor de três terminais com um contato deslizante que forma um divisor de tensão ajustável. Se apenas dois terminais forem utilizados, uma extremidade e o limpador, ele atua como um resistor variável ou reostato. Um instrumento de medição do potenciômetro é essencialmente um divisor de tensão usado para medir o potencial elétrico; O componente é uma implementação do mesmo princípio, daí o seu nome. Os potenciômetros são comumente usados para controlar dispositivos elétricos, como controles de volume em equipamentos de áudio. Os potenciômetros operados por um mecanismo podem ser usados como transdutores de posição, por exemplo, em um joystick. Os potenciômetros raramente são usados para controlar diretamente o poder significativo, já que a potência dissipada no potenciômetro seria comparável à potência na carga controlada.
definição de potentiometer no dicionário inglês
A definição de potenciômetro no dicionário é um instrumento para determinar uma diferença de potencial ou força eletromotriz, medindo a fração dela que equilibra uma força eletromotriz padrão. Outra definição de potenciômetro é um dispositivo com três terminais, dois dos quais estão conectados a um fio de resistência e o terceiro a uma escova que se move ao longo do fio, de modo que um potencial variável pode ser apagado: usado em circuitos eletrônicos, especialmente como um volume ao controle.
