Given :
There is No key given in the diagram.
we can just calculate the current for the whole circuit.
As we can see all the resistance R1 and R2 [top] are in parallel and resistance R3 and R4 [bottom] are in parallel.
1/R1eff= 1/R1+1/R2
=1/6+1/6
=2/6
=1/3
Reff1=3 ohms
In the same way Reff2=3ohms.
Total reistance= R1eff+R2 eff
=3ohms+3ohms
=6ohms.
By ohm's law, we have :
V=IR
I=V/R
=6/6
=1 ampere
∴current=I= 1 A
