MCQ
In the figure, potential difference between $A$ and $B$ is......$V$
- A$5$
- ✓$10$
- C$0$
- D$15$
✓
Answer
Correct option: B.
$10$
b
$\frac{30-\mathrm{V}_{\mathrm{A}}}{10}+\frac{0-\mathrm{V}_{\mathrm{A}}}{10}+\frac{0-\mathrm{V}_{\mathrm{A}}}{10}=0$
$\frac{30-\mathrm{V}_{\mathrm{A}}}{10}+\frac{0-\mathrm{V}_{\mathrm{A}}}{10}+\frac{0-\mathrm{V}_{\mathrm{A}}}{10}=0$
$3=\frac{3 V_{A}}{10}$
$\mathrm{V}_{\mathrm{A}}=10 \mathrm{V}$
