If each of the resistance of the network shown in figure is R, the equivalent resistance between A and B is

A

3R

B

5R

C

R/2

D

R

Text Solution

Verified by Experts

The correct Answer is:
D

The given circuit (a) is redrawn in (b). This circuit is a balanced wheatstone bridge circuit. Hence point C and D are at the same potential. So the resistance R connected between C and D will not contribute anything. hence the equivalent resistance between A and B will be R as shown in figure (c).
