Explanation / Answer

let current from 12v =i1 current from 4v =i2 in left loop, apply KVL 6(i2)+8(i1+i2)=4 in right loop,8 4(i1)-6(i2)=12-4 => 4(i1)-6(i2)=8 solving, i1=1.3 i2=-.46 a>4 v battery= v*i2=4*-.46-1.84 J 12 V = battery=v*i1=12*1.3=.0156 KJ b>resistors i^2r 8 =.84^2*8=5.6448 5 =.46^2*5=1.058 1 =.46^2*1=.2116 3 =1.3^2*3=5.07 1 =1.3^2*1=1.69 c>net enrgy transformation=sum of energy by resistor=add all above values=13.67*10_3 KJ
