Question

In an A.C. circuit a capacitor of $1\mu F$ value is connected to a source of frequency 1000 rad/sec. The value of capacitive reactance will be

• A. $10\Omega$
• B. $100\Omega$
• C. $1000\Omega$
• D. $10,000\Omega$

Answer 1

The correct option is C $1000\Omega$

$\begin{array}{c}c=1\mu f\\ w=1000rad/\sec \\ X_c=\frac{1}{cw}=\frac{1}{1\times {10}^{-6}\times 1000}=1000\Omega \end{array}$

$\therefore$ captive reactance $=1000\Omega$

Hence,

Option $C$ is correct answer.
