R4822= (4.8*2.2)/(4.8+2.2)= 1.51
R482281= (1.51*8.1)/(1.51+8.1)= 1.27
R48228163= 1.27+6.3= 7.57
R1425= (1.4*2.5)/(1.4+2.5)=0.897
R142548228163= (0.897*7.57)/(0.897+7.57)= 0.802Ω
I=E/R = 9/0.802= 11.22A
I14= 9/1.4= 6.4285= 6.43[A]
I25= 9/2.5= 3.6[A]
I63= 9/7.57= 1.1889= 1.19[A]
I48= E4= 9-1.1889*6.3= 1.51V, I48=1.51/4.8= 0.31[A]
I22= 1.51/2.2= 0.69[A]
I81= 1.51/8.1= 0.19[A]
