CAPACITOR BLOCKS DC SUPPLY .THERE ARE MAINLY TWO ANSWERS
1.CAPACITIVE REACTANCE Xc=1/( 2*3.1416*F*C) , HERE THE FREQUENCY OF DC SUPPLY IS ZERO .HENCE THE REACTANCE VALUE IS INFINITY .SO IT BLOCKS THE DC SUPPLY.
2.CURRENT THROUGH A CAPACITOR IS PROPORTIONAL TO THE RATE OF CHANGE OF CURRENT . BUT IN THE CASE OF DC SUPPLY, THE RATE OF CHANGE OF CURRENT IS ZERO. HENCE THE CAPACITOR CURRENT IS ALSO ZERO.

A capacitor is a capacitor, no matter what circuits you use it in. There is no difference between one used in AC and one in DC, except perhaps the size that is appropriate.
An AC-DC converter you can operate a device on AC instead of batteries. ~bobbyjack~ : D
capacitor is component used to store and release the electric charge.and also it has feature to block the dc but bypass ac.and inverter is device which converts ac to dc and then again ac
If a circuit is grounded through a capacitor it is referred to as AC ground because ac signal can pass through the capacitor DC level is blocked
capacitors at input block dc and allows ac only. so absolute none of the dc enters the circuit. They are called decoupling capacitors or blocking caps. -DANNY S
A capacitor blocks DC but allows AC.
It allows AC current to go through, but blocks DC current.
Simply how capacitor blocks dc and allows ac after charging?
Always DC.
A capacitor conducts AC but do not conduct DC because it is meant to store charge.
A capacitor is a capacitor, no matter what circuits you use it in. There is no difference between one used in AC and one in DC, except perhaps the size that is appropriate.
simple capacitor can do this job (to block dc and pass ac).

It filters ac to pure dc
If a circuit is grounded through a capacitor it is referred to as AC ground because ac signal can pass through the capacitor DC level is blocked
A capacitor allows AC (to pass through) because capacitors resist a change in voltage.. The capacitor need change resist in Input signal
