"please have a look at the fallowing details."

Explanation:

"capacitive reactance equation can be written as:"

"if we write this equation for two different situation ,we get: "

X_C=1/(omega C) " (1)"

X_X=1/(omega 3C)" (2)"

"if we find the ratio of (1) and (2),we get: "

(X_C)/(X_X)=1/(cancel(omega C))*(3 cancel(omega C))/1

(X_C)/(X_X)=3

X_X=(X_C)/3

"capacitive reactance will decrease"
