Question

11.if an equilateral triangle is made of 18 ohm resistance wire, than what will be the equivalent resistance between any two vertices.​

Answer 1

=6 ohms But across any two vertices Two resistors series are in series Hence total resistance is 6 + 6 =12 ohms It is in parallel with 6 ohm resistor Hence finally it will be 12 × 6 / 12 + 6 = 4 ohms
