Capacitor contains a dielectric sandwitched between two plates.
So, it act as a charge storage device.
When dc supply is given,it gets charged to its maximum capacity or potential equal to the supply, and then it act as a open circuit, since it has no way to discharge.

Why capacitor in transistor amplifier circuit at input?
Because capacitor not allow to pass dc voltage,but capacitor allow ac voltage and signal.Purpose is to block dc voltage.That is coupling condenser.
Can a non polarized capacitor be connected to a direct current circuit?
Yes, you can connect a polarized capacitor to a direct current. Make sure you get your polarization is correct.A non polarized capacitor can be connected in a DC circuit as well. "Non Polarized" just means it does not matter which side of the capacitor is positive. If you attempt to connect a polarized capacitor in a DC circuit backwards, you will know when the capacitor explodes.
What is the function of mylar capacitor?
In electronic circuits a capacitor is used to pass AC and block DC.
What devices can be used to block DC and pass AC?
simple capacitor can do this job (to block dc and pass ac).
What happens when you apply DC directly to a capacitor?
When you apply DC directly to a capacitor, it charges to the value of the DC potential, and then there is (nearly1) zero current flow through the capacitor. If the capacitance is large enough, though, and the DC source has a low enough impedance, the current flow can be quite substantial, damaging things.The reason the equilibrium current is zero is that a capacitor resists a change in voltage, proportional to current and inversely proportional to capacitance...dv/dt = i/c... which makes the capacitor essentially a high pass filter, and a DC blocker.1 The equilibrium current is "nearly" zero because, in our non-ideal world, every capacitor has some leakage current. Practically, the current is zero - from a purist perspective, it is not.
What is dc link capacitor?
when the DC current flows through the capacitor .the leakage of the charges is in capacitor called Dc leakage capacitor .
What capacitor blocks either ac or DC?
Always DC.
Can capacitor work in dc?
Yes.
When DC power is first applied to an uncharged capacitor it appears as a?
When DC power is first applied to an uncharged capacitor it appears as a short circuit.
Will a capacitor lower voltage?
A: As soon as a DC voltage is applied the capacitor is a short or no voltage
Why the capacitor stores energy in the form of DC though it does not allow DC?
DC does not flow through a capacitor because there is no electrical connection between the plates; they are separated by an insulator calibrated for capacitance.
The electric device which blocks DC?
It is capacitor
Can we use AC capacitor in surge suppression circuit DC?
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.
What is an electrical capacitor?
Electricity is either alternating current or direct current, abbreviated AC or DC. An AC/DC Capacitor can be used in either an AC or DC current.
What will happen if the capacitor is removed from the DC charger?
It will increase the ripple factor that the capacitor is in the circuit to smooth out.
DC blocking in a transistor is achieved by?
Including a series capacitor in the input and/or output circuit of the transistor. If the capacitor in the output circuit is omitted there will be a dc component in the output.
What type of function of capacitor in dc power supply?
It filters ac to pure dc
