Question

the frequency of ac is doubled , what happens of a) Inductive reactance b)capacitive reactance with frequency of alternating frequency 


Solution

Xc= 1/2PiFc

if we double the the F = frequency we can see the Xc= capacitive reactance will decrease by 1/2.

inductive reactance is proportional to frequency( XL α ƒ ) so if frequency doubled the inductive reactance will also become double.
