The physical form and construction of practical capacitors vary widely and many capacitor types are in common use. Capacitors are widely used in electronic circuits for blocking direct current while allowing alternating current to pass. In analog filter networks, they smooth the output of power supplies.

$begingroup$ Correct me if I am wrong, but how does the capacitor pass current when it is in series with an AC signal source? The current "passes" but not in the way that you expect. Since the voltage changes sinusoidally, the voltages also changes across the capacitor, which gives rise to an EMF that induces a current on the other side of the capacitor.
The Vs is the sine wave source and R1 is the internal resistance. The capacitor C is the Ideal capacitor whereas the R2 is the Equivalent Series Resistance of the ideal capacitor C.

If you see one of these next to a terminal, the capacitor is polarized. Make sure to connect the capacitor''s + end to the positive side of the circuit, or the capacitor could eventually cause a short or even explode. If there is no + or -, you can orient the capacitor either way. Some capacitors use a colored bar or a ring-shaped depression to ...
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 from its electronic symbol. In a DC circuit, a capacitor acts as an open circuit and does not permit current to pass.
Capacitors do not so much resist current; it is more productive to think in terms of them reacting to it. The current through a capacitor is equal to the capacitance times the rate …
