Question

Which of the following curves shows correct variation of capacitive reactance $X_C$ with frequency $v$ ?

• A.
• B.
• C.
• D. ****

Answer 1

Answer: (D)

We know that, capacitive reactance,
$X_C=\frac{1}{\omega C}=\frac{1}{2\pi vC}$
$\Rightarrow X_C\propto \frac{1}{v}$
Hence, graph shown in option (d) represents correct variation of $X_C$ with $v$
