In wheat stone bridge circuit `P=7, Q=8, R=12 & s+7.` Find the additional resistance to be used in series with S, so that the bridge is balanced.

In a Wheatstone bridge circuit, P=5 Omega, Q=6 Omega, R=10 Omega and S= 5 Omega . Find the additional resistance to be used in series with S, so that the bridge is balanced.

Three resistance P, Q, R each of 2 Omega and an unknown resistance S from the four amrs of a Wheatstone's bridge circuit. When a resistance of 6 Omega is connected in parallel to S the bridge gets balanced. What is the value of S ?

Three resistances P,Q,R each of 2 Omega and unknown resistance S form the four arms of a Wheatstone bridge circuit. When a resistance of 6 Omega is connected in parallel to S the bridge gets balanced.What is the value of S ?
