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
