What is the maximum charge a capacitor stores?
The maximum charge a capacitor stores depends on the voltage V0 V 0 you've used to charge it according to the formula: Q0 = CV0 Q 0 = C V 0 However, a real capacitor will only work for voltages up to the breakdown voltage of the dielectric medium in the capacitor.
How do you charge a capacitor?
To charge a capacitor, a power source must be connected to the capacitor to supply it with the voltage it needs to charge up. A resistor is placed in series with the capacitor to limit the amount of current that goes to the capacitor. This is a safety measure so that dangerous levels of current don't go through to the capacitor.
Will a capacitor charge up to a rated voltage?
A capacitor will always charge up to its rated charge, if fed current for the needed time. However, a capacitor will only charge up to its rated voltage if fed that voltage directly. A rule of thumb is to charge a capacitor to a voltage below its voltage rating.
Is there a maximum charge for an arbitrary capacitor?
There is no maximum charge for an arbitrary capacitor. Highly active question. Earn 10 reputation (not counting the association bonus) in order to answer this question. The reputation requirement helps protect this question from spam and non-answer activity.
Can You charge a capacitor with a lower voltage?
A rule of thumb is to charge a capacitor to a voltage below its voltage rating. If you feed voltage to a capacitor which is below the capacitor's voltage rating, it will charge up to that voltage, safely, without any problem. If you feed voltage greater than the capacitor's voltage rating, then this is a dangerous thing.
