How does the capacitor work? What does it do?
Straight to pass on the circuit need to pass the AC signal, power supply filter, cut off DC and other places to use. Capacitor charge and discharge is the basis of other properties. There are two kinds of filtering, one is the power filter, which is more obvious charge and discharge, can be seen as a container.
The bypass capacitor is an energy storage device that provides energy to the local device, which can equalize the output of the regulator and reduce the load demand. Like a small rechargeable battery, the bypass capacitor can be charged and discharged to the device. To minimize the impedance, the bypass capacitor should be as close as possible to the load device's power supply pin and ground pin.
The other is the signal filter, that is, the case of alternating current, but also in the AC electrode polarity changes in the process of continuous charge and discharge, in order to AC, if not the capacitance of the two sheds with the amount of change, no matter how the AC can not pass.
Capacitance works: the principle of charge and discharge simply put the capacitor is the two poles charged or discharge, that is, charge diffusion. Charge and discharge capacitors should be connected in series, can be connected in parallel; it is the basis of other properties of capacitance. The phenomenon of intermittent communication is the embodiment of charge and discharge, if it is DC, charged to stop, the capacitor charged; if it is alternating current, is constantly charging discharge. Complete the transmission of AC.
