In a typical wheatstone network the resistance in cyclic order are A=`10Omega,B=5O,ega,C=4Omega` and `D=4Omega` for the bridge to be balanced.
A. `10 Omega` should be connected in parallel with A
B. `10Omega` should be connected in series with A
C. `5Omega` should be connected in series with B
D. `5Omega` should be connected in parallel with B.
