Current through each resistor :- I1-395.41mA , I2-172.62mA , I3-568.03mA

anonymous · Answer

Power delivered - Pr1-4.38W , Pr2-0.36W , Pr3-6.78W

Loop 1:-

-14+23=28i1+(i1-i3)12

9=40i1-12i3-------(1)

Loop 2:-

14=(i3-i1)12+21i3

14=33i3-12i1------(2)

Solving (1) and (2)

i1=395.4mA

i3=568mA

i2=(i3-i1)

i2=172.6mA

Now Power

p1=i1^2*R=(395.4m)^2*28=4.38W

p2=i2^2*R=(172.6m)^2*12=0.36W

p3=i3^2*R=(568m)^2*21=6.78W
