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

Step-by-step solution

The circuit can be shown as given below The equivalent resistance between and aligned R_ D C &= 15 (15+15) 15+(15+15) = 15 30 15+30 &= 15 30 45 =10 aligned Now, between and the resistance of upper part R ₁=15+10+15=40 Between and, the resistance of middle part R ₂=15+15=30 Therefore, equivalent resistance between and aligned 1 R ^ &= 1 R ₁ + 1 R ₂ + 1 R ₃ = 1 40 + 1 30 + 1 15 &= 3+4+8 120 = 15 120 R ^ = 120 15 =8 aligned
