загальний опір резисторів = 0.48 Ом.
I1=0.48 Oм.
I2=0.24 Ом.
I3=0.16 Ом.
I4=0.12 Ом.
Объяснение:
При параллельном соединении справедливо
1/Rобщ= 1/R1 + ...+.1/Rn
1/Rобщ=1+1/2++1/3+1/4=(12+6+4+3)/12=25/12
Roбщ=12/25=0.48 Ом.
Общий ток распределяется по сопротивлениям обратно пропорционально
То есть, чем больше сопротивление, тем меньше ток.
При параллельном соединении:
I1R1=I2R2=I3R3=I4R4=Iобщ*Rобщ
Отсюда
I1=Iобщ*Rобщ/R1
I1=1*0.48/1=0.48 Oм.
I2=I1/2=0.24 Ом.
I3=0.16 Ом.
I4=0.12 Ом.
Проверка
I1+I2+I3+I4=1 A.
0.48+0.24+0.16+0.12=1
1=1 - истина
