" RESISTANCE "

When two resistances are connected in parallel then the equivalent resistance is __. When one of the resistance is removed then the effective resistance is 2Omega . The resistance of the wire removed will be

Less resistivity : Conductor :: High resistivity: ____________

A number of cells of negligible resistance are connected with battery of 12V with two resistances in series.A voltmeter of resistances 5000 Omega while connected with these two resistances reads 4V and 6V respectively.Find the magnitude of the resistances.

Three resistors each of resistance 10 ohm are connected, in turn, to obtain (i) minimum resistance (ii) maximum resistance. Complete (a) The effective resistance in each case (b) ratio of minimum to maximum resistance so obtained.

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) -
