The equivalent resistance between the points A and B will be (each resistance is 15 )

Options

Correct answer

B. 8

Step-by-step solution

Redrawing the given circuit network as Equivalent resistance between points D and C , R_ D C = (15+15) 15 (15+15)+15 = 30 15 45 =10 Similarly, R_ A B =R_ D C =10 Now, circuit, diagram reduces as Equivalent resistance between points A and B is given as aligned R_ A B =(15+10+15) |10=40 | 10 &= 40 10 40+10 &= 400 50 =8 aligned
