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

1. 12Ω
2. 2Ω
3. 6Ω
4. 3Ω

Correct answer: 6Ω

Solution

When three resistances of 4Ω each are connected in a triangle, the equivalent resistance between any two terminals is calculated by considering two resistances in parallel and one in series. The equivalent resistance is 6Ω.
