You charge all capacitors the same way - you apply a current across them. The equation is dv/dt = i/c.

Why a capacitor does not accept AC?

A capacitor conducts AC but do not conduct DC because it is meant to store charge.


What is fifty microfarads?

Fifty millionths of a farad, abbreviated as 50 uF. Farad is the unit of capacitance. 50 microamps DC flowing for 1 second will charge a 50 uF capacitor to 1 volt.

No, auto batteries are DC not AC.


Can capacitor store charge from ac source?

Yes. A capacitor stores charge from any source, including AC.The difference between DC and AC, however, is that the capacitor will be constantly changing in charge, in step with the AC. Due to the nature of the capacitor, the current through the capacitor will lead the voltage by some amount, depending on capacitance and resistance. {In the ideal case of a perfect capacitor, conductors, and AC power source, the current will lead the voltage by 90 degrees phase angle.}This is called capacitive reactance.Another way for a capacitor to store charge from an AC source, of course, is to place a rectifier diode in front of the capacitor. This, then, becomes an AC to DC converter.


How do you charge a capacitor?

You charge a capacitor by placing DC voltage across its terminal leads. Make sure when using a polarized capacitor to place positive voltage across the positive lead (the longer lead) and negative voltage across the negative lead. Also make sure that the voltage you charge the capacitor to doesn't exceeds its voltage rating.


What is the value of capacitor in clamper circuit?

A capacitor is used to restore the DC charge for shifting the DC level of the AC signal. ie. it helps to maintain the level depending on the its time constant.


Why capacitor does not store alternate current but store direct current?

Because Alternet current has both positive as well as negative cycle capacitor does not conduct for negative cycle of the Alternet current and DC all are positive cycle thats why it capacitor conduct for DC not for AC


What is the voltage obtained when a capacitor is placed in a dc circuit?

Eventually, the capacitor will charge to approximately the source voltage level. As this occurs, the current in the circuit will drop to near zero.
