#"please have a look at the fallowing details."#

#"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"#
