Question

Three resistances each of 4 Ω are connected to form a triangle. The resistance between any two terminals is:

G1 Physics · Accepted Answer

Step 1: Between two vertices, one direct branch has 4 Ω. Step 2: Other branch includes the remaining two 4 Ω edges in series, giving 8 Ω. Step 3: Equivalent R = (4×8)/(4+8) = 32/12 = 8/3 Ω.
