KCL in DC circuits:
According to Kirchhoff’s current law (KCL), the algebraic sum of the electric currents meeting at a common point is zero. I.e. the sum of currents entering a node is equal to the sum of currents leaving the node. It is based on the conservation of charge.
KCL in AC circuits:
The Kirchhoff’s current law as applied to the ac circuit is defined as the phasor sum of currents entering the node is equal to the phasor sum of currents leaving the node.
Calculation:
KCL at Node A
I1 + 1A = 3A
I1 = 2 A
KCL at node B
I2 + 2A = 6A
I2 = 4 A
KCL at node C
I3 = 4A + 2A
I3 = 6A
KCL at node D
I = 6A - 5A = 1 A
