Группа резисторов R₄, R₅, R₆ соединены последовательно:
R₄₅₆ = R₄ + R₅ + R₆ = 6 + 2 + 4 = 12 (Ом)
Группа R₄₅₆ и резистор R₃ соединены параллельно:
R₃₄₅₆ = R₃R₄₅₆/(R₃+R₄₅₆) = 4 · 12 : 16 = 3 (Ом)
Группа R₃₄₅₆ и резисторы R₁ и R₂ соединены последовательно.
Общее сопротивление цепи:
R = R₁ + R₂ + R₃₄₅₆ = 2 + 1 + 3 = 6 (Ом)
Общий ток в цепи:
I = I₁ = I₂ = I₃₄₅₆ = U/R = 36 : 6 = 6 (A)
Напряжение на R₃₄₅₆:
U₃₄₅₆ = I · R₃₄₅₆ = 6 · 3 = 18 (B)
Ток через R₄:
I₄ = I₄₅₆ = U₃₄₅₆/R₄₅₆ = 18 : 12 = 1,5 (A)
а разве не проще самим придумать?
Объяснение:
The last film I watched was "fantastic critters, and where they inhabit". This movie is about what the main character wants to save, and save a fantastic world, among people. In this he is helped by two golduns, and a man. But that's what's stopping them. But in this they are hindered by the president/mayor of the city(countries.) Says these creatures are quite dangerous for World. That's why she starts to set up the creatures, which prevents her main character. I advise you to see it!
