MCQ
In the given figure, the equivalent resistance between the points $A$ and $B$ is ............ $\Omega$
- A$8$
- ✓$6$
- C$4$
- D$2$
✓
Answer
Correct option: B.
$6$
b
(b) ${R_{AB}} = {R_1} + \frac{{{R_2}{R_3}}}{{{R_2} + {R_3}}} + {R_4}= 2 + \frac{{4 \times 4}}{{4 + 4}} + 2 = 6\,\Omega $.
(b) ${R_{AB}} = {R_1} + \frac{{{R_2}{R_3}}}{{{R_2} + {R_3}}} + {R_4}= 2 + \frac{{4 \times 4}}{{4 + 4}} + 2 = 6\,\Omega $.
