A skeleton tube is made of 12 wires each of resistance ROmega is connected to a cell of emf E and of negotiable internal resistance. Use Kirchhoff's laws to find the resistance between:- diagonally opposite corners of the same face of the cube is across face diagonal.

Find the angle between any two diagonals of a cube.

Twelve wires ,each of resistance 6 Omega are connected to form a cube. The effective resistance between two diagonally opposite corners of the cube is

A uniform wire of 16 Omega is made into the form of a square. Two opposite corners of the square are connected by a wire of resistance 16Omega . The effective resistance between the other two opposite corners is

In the network shown in the figure, each of the resistance is equal to 2Omega . The resistance between the points A and B is

The effective resistance between A and B in the figure is (7)/(12)Omega if each side of the cube has 1 Omega resistance. The effective resistance between the same two points, when the link AB is removed, is

Choose correct alternative. A thin, uniform wire of resistance 40 Omega is bent to form a circle. The resistance between any two diametrically opposite points is A. 10 Omega B. 15 Omega C. 20 Omega D. None of the above

A potentiometer wire of length 1m and resistance 10 Omega is connected in series with a cell of emf 2V with internal resistance 1 Omega and a resistance box including a resistance R. If potential difference between the ends of the wire is 1 mV, the value of R is

A circuit consists of two cells, each of e.m.f. E and internal resistances r_(1) and r_(2) are connected in series through an external resistance X. If the potential difference between the ends of the first cell is zero, the value of X in terms of r_(1) and r_(2) will be
