Question

If capacitance of capacitor in ac circuit is increased 3times its initial value then capacitive reactance will decrease or increase and how many times?

Answer 1

`"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"`
