21.6 DC Circuits Containing Resistors and Capacitors
Capacitors, like batteries, have internal resistance, so their output voltage is not an emf unless current is zero. This is difficult to measure in practice so we refer to a capacitor''s voltage rather than its emf. But the source of potential difference in a capacitor is
Resistance of capacitors
A capacitor has an infinite resistance (well, unless the voltage gets so high it breaks down). The simplest capacitor is made from two parallel plates with nothing but space in between - as you can guess …

Why does an inductor behave as a capacitor at high frequencies?
Basically, any real inductor can be though of an ideal inductor that has a resistor in series with it (wire resistance) and a capacitor in parallel with it (parasitic capacitance). Now, where does the parasitic capacitance come from? an inductor is made out of a coil of insulated wire, so there are tiny capacitors between the windings …
19.5: Capacitors and Dielectrics
The unit of capacitance is the farad (F), named for Michael Faraday (1791–1867), an English scientist who contributed to the fields of electromagnetism and electrochemistry. Since capacitance is charge per unit voltage, we see that a farad is a coulomb per volt, or

Does a capacitor have a resistance?
A capacitor does have some resistance in practical sense. Whenever a capacitor gets charged, current flows into one of the plates and current flows out of the other plate and vice versa. These plates are usually made of aluminium foil and possess some resistance.
