Электричество Современная электронная теория- вид материи как в основном электричество и атом, элементарная единица материи как состоящая из отрицательных зарядов (электронов), положительных зарядов (протонов) и нейтральных частиц(нейтронов). Внутри атома электроны движутся по орбитам вокруг ядра, а иногда и передвигаются в другой атом. Потерянный электрон покидает атом заряженый положительно: коэффициент усиления электрона заряжает его отрицательно. Статическое электричество связано с природой, силу и влияние заряда на органы заряда тела включают приближение его к заряженному телу растирая стеклянной палочкой с шелком и потереть твердый резиновый стержень с фланелью. принимать и удерживать заряд меняется. Некоторые называют металлы хорошими проводниками передают заряд быстро , некоторые другие материалы являются плохими проводниками. В твердых проводниках ток зависит от движения многих электронов. В электролитических и газообразные проводники как положительные, так и отрицательные заряды двигжутся в любую сторону от электрода к электроду. Электрический ток (поток электронов или) устанавливается в проводнике при подключении сотового электродов, образующих замкнутую электрическую цепь. Одно направление потока электронов называется прямой. Генератор тока(если коммутатор не используется) чередуется направление потока (тока). Такой ток называется переменным током.
