3. Solution.

5. For a network of figure determine the current 4ohm resistance using mesh analysis.

6. Solution:

7. So there are virtually two meshes now mesh i2 and super mesh writing KVL for the two loops meshes we have
6i2+4(i2-i3)+2(i2-i3)=0
Or -2i1+6i2-i3=0
For super mesh
2(i1-i2)+4(i3-i2)+2i3=8
i1-3i2+3i3=4
The current source branch is common to mesh 1 and 3 and hence ,
i1-i3=3
On solving the equation above equation
We get
i1=4A ,i2=1A,i3=1A
Therefor the current is 4 ohm resistor
=i2-i3
=1-1 =0
