Why inductor short on dc and capacitor allow to flow ac?

Answer Posted / bvyankatesh

1.inductor- R=2pieFL in which R is direcly proportional to frequency bt in case of DC f is zero so no resistance offered to DC current flow bt it will be infinite high frequency AC current.
2.capacitor- R=1/2pieFC in which R is inversely proportional to frequency. in case of DC F is zero do infinite R is offered to DC current flow, therefore it allows to flow only AC one.
