The concept of equipotential surfaces is used in this case.
The conducting wire connected with point B will have same potential as that of B.
So, we can take the three points to be 1 and mark all of them as "B"
After redrawing the circuit
We get a simple circuit..and the potential between A nd B can be found.

Ur welcome ✌

akansha20006998: I mean the resistance can be found...

meghanakondeboina: no we have to find current

meghanakondeboina: the answer is 2 amperes

akansha20006998: The que. says resultant resistance b/w A and B not the current.
U may read the que. again

akansha20006998: U should be clear with what u r asking..

meghanakondeboina: sorry but the answer was 2

akansha20006998: My ans is also 2....If u could see the picture in which I have solved the sum.
