Capacitor Basics: How do Capacitors Work?
When discussing how a capacitor works in a DC circuit, you either focus on the steady state scenarios or look at the changes in regards to time. However, with an AC circuit, you generally look at the response of a circuit in regards to the frequency. This is because a capacitor''s impedance isn''t set - it''s dependent on the frequency.
