Kindly tell overall resistance step by step
Q. Equivalent Resistance between P & Q?

Dear Student ,
Here in the upper branch and lower branch two resistors of value R are in series and in the middle branch two resistors of value 2r in also series then their equivalents are in parallel with each other in three branches .
So hence the equivalent resistance of the circuit between the points P and Q is :
1RPQ=1R+R+12r+2r+1R+R1RPQ=12R+14r+12R1RPQ=1R+14rRPQ=4rRR+4r
Regards
