Question

The graph given below depict the dependence of two reactive impedances $X_1$ and $X_2$ on the frequency of the alternating e.m.f. applied individually to them. We can say that:

• A. $X_1$ is an inductor and $X_2$ is a capacitor
• B. $X_1$ is a resistor and $X_2$ is a capacitor
• C. $X_1$ is a capacitor and $X_2$ is an inductor
• D. $X_1$ is an inductor and $X_2$ is a resistor

Answer 1

The correct option is C $X_1$ is a capacitor and $X_2$ is an inductor

As we know,

$X_C=\frac{1}{C\times 2\pi f}$

hence from the above figure $X_{!}$is a capacitor and

$X_L=L\times 2\pi f$

hence $X_2$ is an inductor.
