If `P=Q=R=10 Omega and S=20 Omega`, then what resistance should be joined with S to balance the wheatstone's network ?

Join a resistance of `10 Omega` in series with S

Join a resistance of `10 Omega` in parallel with S

Join a resistance of `20 Omega` in parallel with S

Join a resistance of `20 Omega` in series with S

Text Solution

Verified by Experts

The correct Answer is:

To make `S=10 Omega`, we have to join a resistance of `X= 20 Omega` across S.
