MCQ

Of the following about capacitive reactance which is correct?

A
The reactance of the capacitor is directly proportional to its ability to store charge
✓
Capacitive reactance is inversely proportional to the frequency of the current
C
Capacitive reactance is measured in farad
D
The reactance of a capacitor in an $AC$ circuit is similar to the resistance of a capacitor in a $DC$ circuit

✓

Answer

Correct option: B.

Capacitive reactance is inversely proportional to the frequency of the current

Capacitative reactance is an opposition to the change of voltage across an element.
It is denoted by $XC$ and is inversely proportional to the signal frequency $(f)$ and the capacitance $C$
$\text{X}_\text{c}=\frac{1}{2\pi\text{fc}}$
