In a Wheatstone's network`, P=2Omega, Q=2Omega, R=2Omega and S=3Omega. `The resistance with which S is to be shunted in order that the bridge may be balanced .

Three resistors 1Omega , 2Omega and 3Omega are combined in series. What Is the total resistance of the combination?

The resistances of the four sides of square ABCD are 10Omega, 5Omega, 7Omega and 3Omega in that order. A resistance of 10Omega is connected in between A and C . Calcualte the equivalent resistance between A and B.

Three resistors 1 Omega , 2 Omega and 3 Omega are combined in series. What is the total resistance of the combination?

Three resistors 2Omega , 4Omega and 5Omega are combined in parallel. What is the total resistance of the combination?

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 resistors 2 Omega , 4 Omega and 5 Omega are combined in parallel. What is the total resistance of the combination?

Two cells, E_(1) and E_(2) of emfs 4 V and 8 V having internal resistances 0.5 Omega and 1.0 Omega respectively are connected in opposition to each other. This combination is connected in opposition to with resistance of 4.5 Omega and 3.0 Omega . Another resistance of 6 Omega is connected in parallel across the 3 Omega resistor. Draw the circuit diagram

A short circuit occurs in a telephone cable having a resistance of 0.45 Omega m^(-1). The circuit is tested with a Wheat stone bridge network have values of 100 Omega and 1,110 Omega respectively. A balance condition is found when the variable resistor has a value of 400 Omega. Calculate the distance down the cable, where the short has occured.
