MCQ
Find the value of $I$ ?................ $\mathrm{A}$
- A$-1.4$
- ✓$-2.1$
- C$2$
- D$-4.2$
✓
Answer
Correct option: B.
$-2.1$
b
in loop $\mathrm{ABEFA}$
in loop $\mathrm{ABEFA}$
$I_{1}=\frac{8}{5} \,A=1.6 \,A$
in loop $\mathrm{BCDEB}$
$I_{1}=\frac{3}{6}=0.5 \mathrm{\,A}$
$\mathrm{I}=-\left(\mathrm{I}_{1}+\mathrm{I}_{2}\right)$
$\mathrm{I}=-2.1 \mathrm{\,A}$
