But it will not satisfy the KCL Law, right? can anyone please explain?

It is known that current across the capacitor is led 90 from applied voltage according to the phasor diagram of current across RC circuit is equal to the diagonally resultant so A2= √(A1^2-A3^2).

So here KCL violates?
I think its 8.
I think its 8.

By Vector Analysis, currents through capacitor and resistor get added vector.
Therefore sqrt(ic^2+ir^2) = i, which is source current. Here I and IR are given substitute to find IC.

Since 3rd ammeter had a source a3 = a1+a2;
= 13 = 5+x;
x = 8.
= 13 = 5+x;
x = 8.
