Question

Два проводника соединены параллельно. Сила тока в первом проводнике 2 А, а во втором 1 А. Какова сила тока в общей цепи?

Answer 1

3а. Просто складываем. Ток разделяется при параллельном соединении в соответствии с сопротивлениями проводников

Answer 2

Calculating Total Current in Parallel Circuit

In a parallel circuit, the total current is the sum of the currents in the individual branches. Given that the currents in the two parallel branches are 2 A and 1 A, the total current in the circuit can be calculated as follows:

Total Current (I_total) = I₁ + I₂

Where: - I₁ = 2 A (current in the first branch) - I₂ = 1 A (current in the second branch)

Total Current (I_total) = 2 A + 1 A = 3 A.

Therefore, the total current in the circuit is 3 A.
