MCQ
Find the current passing through battery immediately after key $(K)$ is closed. It is given that initially all the capacitors are uncharged......$A$ (Given that $R = 6\,\Omega$ and $C = 4\, \mu F$)
- ✓$1 $
- B$5$
- C$3$
- D$2$
✓
Answer
Correct option: A.
$1 $
a
At time $t=0,$ resistance offered by a capacitor $=0$ and resistance offered by an inductor $=\alpha$
At time $t=0,$ resistance offered by a capacitor $=0$ and resistance offered by an inductor $=\alpha$
$R_{n e t}=\frac{R}{2}+\frac{R}{3}=\frac{5 R}{6}=5 \Omega$
$\therefore$ Current from the battery,
$i=\frac{E}{R_{n e t}}=\frac{5}{5}=1 A$
