If a resistor is connected in series with the capacitor forming an RC circuit, the capacitor will charge up gradually through the resistor until the voltage across the capacitor reaches that of the supply voltage. The time called the transient response, required for this to occur is equivalent to about
5 time constantsor
5T
. This transient response time
T
, is measured in terms of
τ= R x C
, in seconds, where
R
is the value of the resistor in ohms and
C
is the value of the capacitor in Farads. This then forms the basis of an RC charging circuit were
5T
can also be thought of as
"5 x RC"
.

Does an electric capacitor store electric charge?
Capacitors store energy in the electric field between their plates. They do not store charge, the net value of which is the same after, as before, charging (they do, however, separate charge).

There are 4 constants.

What electronic components can store charge?
A capacitor and a battery. They both store charges but due to the fact that conventional batteries are chemically-powered, they don't charge or discharge very fast. On the other hand, they can be built to hold large amounts of charge. Conversely, a capacitor doesn't have nearly the same amount of capacity as batteries, but they charge and discharge much faster. For this reason, they are used in many capacities, such as in vehicle ignition systems, charging circuits for conventional digital cameras, and some appliances (and hence why those appliances will urge you to not open them up yourself as you may be exposed to enough charge that will kill you).
Can a capacitor create more Amps than is put into it at high voltages?
You better believe it, otherwise you're in for a surprise. A capacitor is a current storage device, and even when fed by a small charge from a (say) kV supply, it will eventually acquire the full capacitance charge at the charging voltage.The charge is stored as a distortion of the insulating material, and when it discharges, if into a low-resistance circuit, the current will be high.And with high voltage capacitors, there may be a small hysteresis of the dielectric, and this will relax back to a zero stress position only slowly.So you should discharge an HV capacitor several times, waiting a few seconds between discharges.This is a mistake many technicians make, but generally only the once!
How many hours does the remote control for PS3 have to charge?
Mine needs to carge for just one hour and it is fully charged.
How many volts can a capacitor hold. what would be the formula for a capacitor that holds 100 volts?
The working voltage of a capacitor depends on the nature of the dielectric and its thickness. Most capacitors are marked on the case e.g. 500V wkg. or just 150V. Small components are colour coded; the code will tell you the capacitance, and the wkg voltage.
