Question

Corresponding to the figure shown, match the two columns.

Column $\text{I}$	Column $\text{II}$
$a.$ Resistance $b.$ Capacitive reactance $c.$ Inductive reactance $d.$ Impedance	$p.$ $4$ $q.$ $1$ $r.$ $2$ $s.$ $3$

• A. $a\to s;b\to p;c\to r;d\to q$
• B. $a\to p;b\to s;c\to r;d\to q$
• C. $a\to s;b\to p;c\to q;d\to r$
• D. $a\to q;b\to p;c\to r;d\to s$

Answer 1

The correct option is A $a\to s;b\to p;c\to r;d\to q$

We know that resistance does not depend on the value of $\omega$.

$\therefore a\to s$

$X_C=\frac{1}{\omega C}\Rightarrow X_C\propto \frac{1}{\omega }$

$\therefore b\to p$

$X_L=\omega L\Rightarrow X_L\propto \omega$

$\therefore c\to r$

Impedance first decreases with increase in $\omega$ and then increases with increase in $\omega$.

$\therefore d\to q$
