Ответ:
I₁=5A, I₂=3,75A, I₃=1,25A, I₄=1,33A, I₅=2,67A, I₆=1A, I₇=2,5A
U₁=32B, U₂=U₃=15B, U₄=U₅=U₆=8B, U₇=55B
Объяснение:
U₄=U₅=U₆=I*R₆=1*8=8B
I₄=U₄/R₄=8/6=1,33A
I₅=U₅/R₅=8/3=2,67A
I₁=I₄+I₅+I₆=1+1,33+2,67=5A
U₁=I₁*R₁=5*6,4=32B
U₂=U₃=I₁*R₂*R₃/(R₂+R₃)=5*4*12/(4+12)=15B
I₂=U₂/R₂=15/4=3,75A
I₃=U₃/R₃=15/12=1,25A
U₇=U₁+U₂+U₆=32+15+8=55B
I₇=U₇/R₇=55/20=2,5A
