Question

Three resistance each of 4Ω are connected to from a triangle. The resistance b / w two terminal is

विकल्प

• 12 Ω

• 6 Ω

• `8/3` Ω

• 2 Ω

Answer 1

`8/3` Ω

Explanation:

The resistance of two triangle arms will be in series (4 + 4 = 8Ω). This resistance will be parallel to the third arm's resistance (= 4Ω).

∴ 

∴ R_AB = `(4 xx 8)/(4 + 8) = 48/12 = (4 xx 8)/(4 xx 3) = 8/3`Ω
