Expert Answer
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
......................... (2)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
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
