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

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.
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 .
Why won't a capacitor conduct DC?
capacitor blocks DC, after it finishes charging. Actually, it resists any CHANGE to DC (ie ac), after it has finished charging. IRT the actual question, current will always flow, as long as there is a closed circuit.
Will voltage drop across a capacitor?
basically a capacitor will charge to the input DC level however it will mathematically never happen since capacitors charge at a certain rate the voltage drop across a capacitor will follow the R C time constant or 63% of the applied voltage for a unit time.AnswerIn the case of an a.c. supply, yes, there will be a voltage drop across a capacitor. In the case of an 'ideal' capacitor, this will be the product of the load current and the capacitive reactance of the capacitor.
What happens if you place a capacitor on a dc motor?
Depending on voltage and amperage needed to run the motor,say,3volts.If you use a 3+volt capacitor what will happen is that the motor will turn once(not rev/min) and stop when the capacitor is completely drained which would occur in about half a second or less. Contributed writer:Dennis Wachira.
Why a capacitor does not accept AC?
A capacitor conducts AC but do not conduct DC because it is meant to store charge.

Will a 120 volt AC to 12 volt AC adapter charge a 12 volt car battery?
No, the battery is DC not AC.
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 .
How charge lead acid batteries for 6 v DC?
Charge them with a 6 volt battery charger.
How long does it take to charge a 12 volt DC battery?
approx 6hrs
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.
Will a 120 volt AC to 12 volt AC adapter charge a car battery?
No, auto batteries are DC not AC.
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.
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.
What will happen if two terminals of capacitor are shorted?
When the terminals of a capacitor are connected together, the capacitor will discharge, returning to a zero potential state. Capacitors resist voltage change, meaning that if the capacitor is in a circuit that has zero voltage potential, the capacitor will eventually achieve zero potential. If the capacitor is in a circuit that has a 5 volt potential, the capacitor will seek and attempt to maintain that 5 volt potential (provided that the capacitor is rated at 5 volts or more). In an AC circuit, the capacitor will tend to smooth out the sin wave of the current, resisting change in both directions. In a DC power supply circuit, a capacitor will tend to reduce the voltage "ripple", and if the circuit is designed properly, will provide a smooth DC voltage. Shorting the terminals of a capacitor is effectively what often happens in many circuits; it's not a problem.
