Здравствуйте! Прошу помощи в следующем вопросе:
а) Что называется колебательным контуром? Нарисуйте схему идеального колебательного контура. Изменение напряжения на конденсаторе в колебательном контуре описывается графиком, изображенным на рисунке. По графику определите амплитуду напряжения и период колебаний.
б) Рассчитайте частоту колебаний. Запишите уравнение зависимости напряжения от времени с числовыми параметрами.

это ответ
Амплитуда - в данном случае это максимальное напряжение на конденсаторе Um=20B. Определили по графику.
Период колебаний - время одного полного колебания Т=2мкс = 2*10-6с. Определили по графику.
Частоту [$957$] (ню - греч.буква) посчитаем
[$957$]=1/Т=0,5*106Гц.
Циклическая частота [$969$]=2[$960$][$957$]=106[$960$] с-1
Общий вид уравнения колебаний напряжения в контуре
u(t)=Um*cos([$969$]t+[$966$]0)
Начальная фаза [$966$]0=0
[$8658$]
уравнение колебаний напряжения в нашем контуре
u(t)=20*cos(106[$960$]t) (B)
Я решил для вас задачу под буквой "б". Исходя из правила: одна задача - одна консультация. Надеюсь, к этому времени вы уже имеете представление о колебательном контуре.
