MCQ
The total currents flowing in the circuit is :
- A4 A
- B6.93 A
- ✓3.69 A
- D5 A
✓
Answer
Correct option: C.
3.69 A
(c)
3.69 A
Explanation:
$2 \Omega$ and $1 \Omega$ are in series
$3 \Omega$ and $3 \Omega$ are in parallel $\downarrow$
$
\begin{array}{l}
\frac{1}{R}=\frac{1}{3}+\frac{1}{3}=\frac{2}{3} \\
\Rightarrow R=\frac{3}{2} \\
=1.5 \Omega
\end{array}
$
And, all resistance are in series
Total resistance $=3+1.5+2$
$
=6.5 \Omega
$
Total current, $I=\frac{V}{R}=\frac{24}{6.5}$
$
=3.69 A
