The basic functions of the capacitor

2015/4/15      view:
Capacitor charging and discharging are the basic functions.
Charge
So that charged capacitor (storage charge and energy) is called charging. Then two plate capacitor is always a positively charged plate and another plate with the same amount of negative charge. The capacitor plate then a power supply (eg battery) is positive, then the power supply to another plate negative, two plates were put on the same amount of the heterogeneous charge. After charging the capacitor between the bipolar plates have a electric field, the charging process to obtain electricity from the power stored in the capacitor.
Discharge
To charge capacitor after the loss of charge (the release of charge and energy) is called discharge. For example, using a wire connected to the capacitor poles, two poles with each other and in charge on the capacitor will charge and release energy. After the capacitor discharge electric field between the disappearance of the bipolar plates, electrical energy into other forms of energy.
In general electronic circuits commonly used to achieve the bypass capacitor, coupling, filtering, oscillation, phase shift and waveform transformation and so on, these effects are the charge and discharge of its functions evolution.
