Akash Anand Wrong answer..keep trying.
Assuming R=2 Ohm
I=
325/7;
we have to use the superposition principle;
when we dont consider the 50 V battery....the two 2ohm resistor at the top will be shorted....so Req=28/13....Iat R= 325/7
when 100 V battery is not considered....the two 2ohm resistors will get shorted...resulting in a wheatstone bridge...therefore current in R=0;
therofore total current through R=325/7
0 A
