Let us apply Kirchoff's voltage law to the loop ABEFA . We get
-0.25 I2 +12 -12 +0.20 I1 = 0
From above circuit , we get , I1 = 1.25 I2 .................. (1)
Let us apply Kirchoff's voltage law to the loop BCDEB
![begin mathsize 14px style I subscript 3 space minus 12 space plus space 0.25 space I subscript 2 space end subscript equals space 0 end style](https://images.topperlearning.com/topper/tinymce/cache/87b823740cb5b45dcda0898195afb5fd.png)
If we apply Kirchoff's curremt law to the juntion B , wegt ,
I3 = I1 + I2 .................... (3)
By using eqn.(1) and eqn.(3) , we rewrite eqn.(2) as
![begin mathsize 14px style 2.5 space I subscript 2 space equals space 12 space space end style](https://images.topperlearning.com/topper/tinymce/cache/72a7cfa107ca5748a0d684f68ca03b88.png)
Hence I2 = 4.8 A ;
From eqn.(1) , we get , I1 = 6 A ;
Hence current passing through 1 Ω resistor is I3 = ( 6 + 4.8 ) A \ = 10.8 A
Power diispation in 1 Ω resitor = I32 R = (10.8 × 10.8 × 1 ) W = 117 W
