MCQ
The angular frequency of an $AC$ source is $\frac{10\text{radian}}{\text{sec}}$ The reactance of $1\mu\text{F}$ capacitor will be.
- A$10^4\Omega$
- B$10^2\Omega$
- C$10^1\Omega$
- ✓$10^5\Omega$
✓
Answer
Correct option: D.
$10^5\Omega$
$\text{Reactance}=\frac{1}{\text{C}\omega}\Omega$
$=\frac{1}{10^{-6}\times10}=\frac{1}{10^{-5}}$
$=10^5\Omega$
$=\frac{1}{10^{-6}\times10}=\frac{1}{10^{-5}}$
$=10^5\Omega$
