How does a capacitor block DC?
Capacitor
Current can resume flowing if an alternate path is opened so that the capacitors can discharge itself or by using an alternating current so that the capacitor is periodically charged and discharged. An important parameter for a capacitor is the capacitance, a measurement of the ability an object has to store charge.

Capacitors that are connected to a sinusoidal supply produce reactance from the effects of supply frequency and capacitor size. Capacitance in AC Circuits results in a time-dependent current which is shifted in phase by …
20.5: Alternating Current versus Direct Current
Alternating Current Most of the examples dealt with so far, and particularly those utilizing batteries, have constant voltage sources. Once the current is established, it is thus also a constant. Direct current (DC) is the flow of electric charge in only one direction. It is ...
What current does a capacitor pass?
ac power (alternating current) it blocks dc power Many people will say a capacitor can''t pass current because they consider Electric current to be the flow of electrons but that''s not ...
Basics of Capacitors [Lesson 1] How do capacitors work?
<Capacitors block the flow of direct current and permit the flow of alternating current.> A capacitor does not allow direct current to pass through it, but when the charging and discharging are repeated, a charging current and discharging current repeatedly flow …
