In the figure shown, A1, A2, A3 are identical Ammeters. If A1 and A3 read 5 and 13 A respectively, reading of A2 will be
8
13 A
18
12 A
Answer: Option
Explanation:

A2 = 132 - 25 12 A.

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).

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.

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

Since 3rd ammeter had a source a3 = a1+a2;

= 13 = 5+x;
x = 8.

Is there any one who could help us with this solution?

So here KCL violates?

I think its 8.
