Why does a real world capacitor behave like an inductor at …
Let''s assume an angular frequency of 1Mhz (approx. 6.2·106 rad/s), a capacitance of 0.1 µF and a typical parasitic inductance for ceramic capacitors, approximately 1nH. In the absence of any parasitic effects, the impedance of such a capacitor would be approximately -j·1.591 Ω.
Capacitor in Electronics
When a capacitor is connected to a power source, electrons accumulate at one of the conductors (the negative plate), while electrons are removed from the other conductor (the positive plate). This creates a potential difference (voltage) across the plates and establishes an electric field in the dielectric material between them.
