MCQ
Three $2\Omega$ resistances are connected so as to make a triangle. The resistance between any two vertices is :
- A$6\Omega$
- B$2\Omega$
- C$\frac{3}{4}\Omega$
- ✓$\frac{4}{3}\Omega$
✓
Answer
Correct option: D.
$\frac{4}{3}\Omega$
$2+2=4\Omega$
this combination is parallel to the third resistance.
Hence effective resistance is
$4\times\frac{2}{4}+2=\frac{8}{6}=\frac{4}{3}$
this combination is parallel to the third resistance.
Hence effective resistance is
$4\times\frac{2}{4}+2=\frac{8}{6}=\frac{4}{3}$
