Combination of Resistors

Three resistances each of $4\ \Omega$ are connected to form a triangle. The resistance between any two terminals is

Show answer and solution

Answer: (d)

Between two corners: one side ( $4\ \Omega$ ) is in parallel with the other two sides in series ( $8\ \Omega$ ).
$R_{eq} = \dfrac{4 \times 8}{4 + 8} = \dfrac{8}{3}\ \Omega$
So the answer is (d) $8/3\ \Omega$ .
