Решение 4. №24 (с. 243)

А) закон сохранения электрического заряда

Закон сохранения электрического заряда утверждает, что алгебраическая сумма электрических зарядов в замкнутой (изолированной) системе остается неизменной. Это означает, что заряды не могут быть созданы или уничтожены, они могут только передаваться от одного тела к другому или перемещаться внутри тела. Для системы, состоящей из нескольких тел (например, трех), этот закон можно записать как сумму их зарядов, которая является постоянной величиной (константой). Формула $q_1 + q_2 + q_3 = \text{const}$ является математическим выражением этого закона для системы из трех зарядов.

Ответ: 3

Б) закон Ома для участка цепи

Закон Ома для участка цепи устанавливает зависимость между силой тока $I$ в проводнике, напряжением $U$ на его концах и сопротивлением проводника $R$. Закон гласит, что сила тока на участке цепи прямо пропорциональна напряжению, приложенному к этому участку, и обратно пропорциональна его сопротивлению. Математически это выражается формулой $I = \frac{U}{R}$.

Ответ: 1

В) закон Джоуля—Ленца

Закон Джоуля—Ленца определяет количество теплоты $Q$, которое выделяется в проводнике при прохождении через него электрического тока. Согласно этому закону, количество выделившейся теплоты прямо пропорционально квадрату силы тока $I$, сопротивлению проводника $R$ и времени $t$, в течение которого ток протекал по проводнику. Математическая формулировка этого закона имеет вид $Q = I^2Rt$.

Ответ: 4
