The Capacitive reactance of a 0.094uF capacitor when a frequency of 25kHz is applied is lus 68 Ohms 0.68 Ohms luf

Nana76 [90]

Answer:

Capacitive reactance of the capacitor is 68 ohms

Explanation:

It is given that,

Capacitance, $C=0.094\ \mu F=0.094\times 10^{-6}\ F$

Frequency, $f=25\ kHz=25\times 10^3\ Hz$

Capacitive reactance is given by :

$X_C=\dfrac{1}{2\pi fC}$

$X_C=\dfrac{1}{2\pi 25\times 10^3\times 0.094\times 10^{-6}}$

$X_C=67.72\ \Omega$

or

$X_C=68\ \Omega$

So, the capacitive reactance of the capacitor is 68 ohms. Hence, this is the required solution.
