Kirchhoff’s Current Law:
It says the total current entering a circuits junction is exactly equal to the total current leaving the same junction.
Or sum of all current entering or leaving a node is zero
According to KCL: ∑I = 0
Applying KCL:
I1 + I2 – I3 – I4 – I5 = 0
I1 + I2 = I3 + I4 + I5
Calculation:
Apply KCL at node 'a'
i0 = 0.5i0 + 3
0.5i0 = 3
i0 = 6 A
∴v0 = 4i0 = 4× 6 = 24 V
