If you do the node analysis on this problem, you get your current to be .769 mA. By splitting the above circuit into two sections with 2 diffferent currents, you also get .769 mA. How do you come to get the answer 1.8 mA ?

24 - 18 = 6v.
Total current through r3.
r3 = 3.3k ohm.
I = V/R.
I = 6/3.3k ohm.
I = 1.80mA.

@Mayur.
Can you help me by explaining how you have calculated Thevenin Voltage?

By using source transformation we get .769 as an answer.

Using superposition.
Current produced by 24V = 11.5A
Current produced by 18V = 8.7A
Resultant current ; 11.5- 8.7 =2.8
Current in R3 3.3 ; 2.8[1.2]/[1.2+3.3] = 0.75A#.

From nodal analysis,
Node voltage is 2.538v.
Current through 3.3Kohm is (2.358/3.3) * mA = .769mA.

The voltage across r3 is24-18 = 6, and current is 6/3.3=1.8.

I got 0.769 mA through 3.3 ohms resistor using KVL, node analysis, superposition according to my view answer is .769 mAmp.
Thanks.
Thanks.

The correct answer is 0.769 mA. I also agree.
