why does a capacitor blok dc but alows ac to pass through?..

Answer / kunal s. thaker

Xc=1/2pieFc

but for d.c. Fc=0

so Xc= infinitive

so capacitor offers infinite resistance and block the D.C.

why does a capacitor blok dc but alows ac to pass through?..

Answer / barsha mohanty

we know thant ,
xc=1/2*3.141*f*c
in dc f(frequency)=0,
so,xc=infinitive,hence it become a open circuit.that's why
capacitor blocks dc.

Answer / ashok

In DC capacitor acts as a Open ckt where as in AC it's
close ckt
due to it's inherent property ( as explined by above
frd)

why does a capacitor blok dc but alows ac to pass through?..

Answer / vinit92

in a.c it has a xc=a/2pifc .in fc has a some finite value
but in d.c. fc is a 0 sp xc will be onfinite so it will be
block dc and pass to ac
and another reason we can say that the in dc has a consatant
current so capacitor will not to be charged but in ac has
alternative current so it will be charged to capacitor
so capacitor will block to dc and pass to ac ,,,,,,,
