Resistance

Two resistances are joined in parallel of which equivalent resistance is 1.2 Omega . One of the resistance wire is broken and the effective resistance becomes 2 Omega , then the resistance of the wire that got broken was :

When two resistance are connected in parallel then the equivalent resistance is (6)/(5)Omega When one of the resistance is removed then the effective resistance is 2Omega . The resistance of the wire removed will be

Two resistances are joined in parallel whose equivolent resistance is 3/5Omega . One of the resistance wire is broken and the effective resistance becomes 3Omega . The resistance (in ohms) of the wire that got broken was

A resistance R_(2) is connected in parallel with a resistance R_(1) what resistance R_(3) must be connected in series with the combination of R_(1) and R_(2) so that the equivalent resistance is equal to the resistance R_(1) -

A galvanometer of resistance 5 Omega is connected in series with a resistance of 0.2Omega to a battery of negligible internal resistance. The deflection is noted. If the 0.2Omega resistance is replaced by 2 Omega resistance, the value of shunt resistance to be connected to the galvanometer to maintain the same deflection is
