Eight resistance each of resistance 5ohm are connected in the circuit shown in figure the equivalent resistance between A and B is

Dear student,

You may use an important theorem for resolving this type of a symmetric circuit.

”The junctions along the symmetric bisector of the line joining A and B can be opened”

From this law, the branch AOB can be seperate from that of the above and then a simple circuit of series and parallel is formed as shown in figure.
