MCQ
The reading of the ammeter as shown in figure
- A$\frac{1}{8}\,A$
- ✓$\frac{3}{4}\,A$
- C$\frac{1}{2}\,A$
- D$2\,A$
✓
Answer
Correct option: B.
$\frac{3}{4}\,A$
b
$\mathrm{R}_{\mathrm{eq}}=\frac{2}{3}+2=\frac{8}{3}, \quad \mathrm{V}=2 \mathrm{\,V} \quad \therefore \mathrm{i}=\frac{\mathrm{V}}{\mathrm{R}_{\mathrm{eq}}}=\frac{3}{4} \mathrm{\,A}$
$\mathrm{R}_{\mathrm{eq}}=\frac{2}{3}+2=\frac{8}{3}, \quad \mathrm{V}=2 \mathrm{\,V} \quad \therefore \mathrm{i}=\frac{\mathrm{V}}{\mathrm{R}_{\mathrm{eq}}}=\frac{3}{4} \mathrm{\,A}$
