How can I approach this type of problem? Which different methods can be used here? KVL, supernode, mesh-analysis, source transform.
I tried using KCL on a node assuming its voltage V1:
2=(V1-10)/1 + (V1-4Vo)/4
Solving we get eqn :
5V1-4Vo=48 ...(1)
How can I form the second equation?
Assuming loop currents i1 and i2 (clockwise),
so i1=-2
Vo=(i2+2)*1 ..(total current is i2+2 isn't it?)
second loop eqn is:
-10-Vo+4i2+4Vo=0
3Vo+4i2=10
3(i2+2)+4i2=10
3i2+6+4i2=10
i2=4/7 Amp (Probably wrong! Why?)
Vo=(4/7)+2= 2.57
4Vo=10.28
Power=(10.28)^2 * (4/7)=Wrong
the 4 answer options are +/- 1152 or +/- 1200
