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.

Eight resistances each of 4 Omega are connected in the circuit as shown in fig. The equivalent resistance between A and B is:

The resistance of each arm of the wheat stone bridge is 10Omega . A resistance of 10Omega is connected in series with galvanometer then the equivalent resistance across the battery will be

A wire of resistance 10Omega is elongated by 10%. The resistance of the eleongated wire is

In a wheatstone bridge, the resistance of the arms of the bridge are AB = 2Omega, BC = 4Omega ,AD = 1Omega and DC = 3Omega. a cell of emf 2volt the terminals of negligible resistance to A and C is connected. If a galvanometer of resistance 10Omega is connected between B and D, find the current in the galvanometer.

The resistance of a conductor of a conductor is 5Omega at 50^@C, and 6Omega at 100^@C . What is its resistance at 0^@C ?

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