Question:
Plot a graph to show the variation of reactance of the element with the frequency of the applied voltage.
Plot a graph to show the variation of reactance of the element with the frequency of the applied voltage.
Show Hint
The inductive reactance increases linearly with frequency. So, in an AC circuit, increasing the frequency increases the opposition to current flow in an inductor.

Solution and Explanation
Since the element identified in part (a) is an inductor, the inductive reactance is given by:
\[
X_L = \omega L = 2\pi f L
\]
where \( f \) is the frequency of the applied AC voltage.
From the formula, it is evident that the inductive reactance \( X_L \) is directly proportional to the frequency \( f \). Therefore, as frequency increases, the reactance increases linearly.
