Please tell this problem.

Use super position theorem first consider dc voltage source open current source.

So i1 = 12/270+120.

Then current source i2 = 150m*270/270+120.

I = i1+i2.

I make use of kcl but not able to get ans.

By using kvl, we can solve the easily final result 134.12.

By using nodal analysis, we can easily get the final result 134 mA.

I1 = I2 - 0.150 ---- 1.

v = 270I1 + 120I2 ---- 2.

12 = 270(I2-0.150) + 120I2

I2 = (12+270*0.150)/390 = 134 mA.

Use of source transformation techniqu make will make the problem easy,120*0.15=18.00v will connected with series with 120 ohm resister and then apply kvl 120i+270i+18-12=-6/390

0=V-12/270+V/120+150
V=16.15
current through R2
I=V/R
I=16.15/120
=134mA

Use nodal analysis, you will get nearer value to option D.

Why we can't apply kcl. I think kcl make it eassy.
