What effect does electric capacity have?

If you want to learn more circuit knowledge, pay close attention to me please, from 0 begin to explain principle plan, wait for you to learn

Capacitance is an electron one of yuan of most parts of an apparatus are used in circuit. Its action has a lot of, we explain one by one.

Capacitance rises to separate the function of straight current communication in coupling circuit, communication signal can be in the induction of other one aspect of the matter of capacitance gives corresponding charge, and dc electric current cannot the induction gives charge.

In the frequency with wave of power source filter and the capacitance will specific circuit that use in all sorts of filter circuit paragraph the signal purify inside, we call filter wave, for instance 50Hz is versed in frequency interference can use capacitance to design a filter filter to divide.

LC paralell connection and series connection need circuit of this kind of capacitance in syntonic circuit.

The capacitor that is used in integral circuit calls integral capacitance. In the synchronous and detached circuit that scans in electromotive force field, use circuit of this kind of integral capacitance, can take from inside signal of pace of field answer contract come on the stage synchronous signal.
