Find the resistance of a wire frame shaped as cube (Fig) when measured between points (a) 1.7, (b) 1.2, (c) 1.3.
The resitance of each edge of the frame is `R`

Five resistance, each of 5Omega are connected as shown in figure. Find the equivalent resistance between points (1) A and B , (2) A and C .

Find equivalent resistance between points A and B in the figure. Each resistance is R.

Four identical resistances are joined as shown in the figure. The equivalent resistance between points A and B is R_(1) and that between A anc C is R_(2) then ratio R_(1)//R_(2) is

Six resistance each of value r=5 Omega are connected between points A, B and C as shown in figure. If R_(1), R_(2) and R_(3) are the net resistance between A and B, between B and C and between A and C respectively, then R_(1):R_(2):R_(3) will be equal to

Find the equivalent resistance of the circuit shown in Fig.4.60 between the points A and B. Each resistor has a resistance r.

There is an infinite wire grid with square cells (Fig). The resistance of each wire between neighbouring joint connections is equal to R_(0) . Find the resistance R of the whole grid between points A and B . Instruction. Make use of principles of symmetry and superposition.
