As a result, the maximum charge that a capacitor can withstand is 13.28x10-9C. 13.28 x 10-9 degrees Celsius is about 250 volts.
This means that a capacitor can only hold a maximum of 250 volts before it starts to damage itself. A capacitor's voltage rating is usually indicated on its case or on its documentation. If it says it can handle up to 500 volts, then it is capable of holding that much energy.
Capacitors are designed to handle high voltages, but they will eventually fail if they are exposed to higher currents for longer periods of time. For example, if a capacitor is not removed from a circuit after it has been charged/discharged then it will soon be destroyed.
In general, capacitors should not be discharged below some small percentage of their value (usually 95% or 99%) because any remaining energy would be very dangerous to people and equipment.
Capacitors are used in many different kinds of circuits to store an electrical charge for later use. This allows computers to work more efficiently than if they had to give out all their power immediately after being turned on.
Any amount of charge may be applied to a capacitor as long as the rated voltage is not exceeded. The maximum charge on the capacitor at its highest allowed voltage is determined by Q=CV. Exceeding this voltage might cause the capacitor to deteriorate or damage due to dielectric breakdown. Cement and paper capacitors should never be fully charged because they will eventually self-destruct. Metal film and hybrid capacitors can be charged as much as 100% of their capacity without harm, but it is recommended that you don't charge them beyond half of their value.
For example, if you were to connect a 1 microfarad capacitor to a circuit with a maximum rating of 2 volts, then the capacitor could hold a maximum of 0.5 microcoulombs of charge. This means that the capacitor could be fully discharged in less than 5 minutes and still remain reliable.
Some people think that you can get more charge into the capacitor by connecting several smaller ones in parallel. This is false; only one cap can be charged up at a time. If you have several small caps connected in parallel, then each one will be able to discharge through all of the other caps, which won't be able to discharge anymore. This would cause some caps to reach their maximum voltage before others, which would likely cause them to break down before anyone else did.
Finally, don't try to charge a capacitor with an amplifier stage using its +B terminal.
This is the current voltage. 2 The capacitor voltage rating is the highest voltage that the manufacturer allows for that item. So, a 10uF 16V capacitor may be charged with a voltage of up to 16V without destroying it, yet approaching 16V is bad engineering practice because it is near to the part's maximum.
A capacitor's maximum charge voltage is its operating voltage minus its breakdown voltage. For example, if the operating voltage is 12V and the breakdown voltage is 15V, then the capacitor can be charged to 12V without breaking down. When charging a capacitor, only charge up to the level shown by the cap's label to prevent damage to it.
As long as you don't try to put more charge on the capacitor than what it can handle, you will be fine. Capacitors like to be pushed but not broken. Trying to break them will only result in damaged parts. Also, take care not to connect two capacitors in parallel if they were not designed to be used this way; this could cause either or both caps to fail prematurely.
2 Only a certain amount of charge can be stored in a capacitor before it becomes partially discharged. As more charges are placed on the capacitor, these previously stored charges are overwritten and lost. This is known as "capacitor saturation".
