21.6: DC Circuits Containing Resistors and Capacitors
RC Circuits. An (RC) circuit is one containing a resisto r (R) and capacitor (C). The capacitor is an electrical component that stores electric charge. Figure shows a simple (RC) circuit that employs a DC (direct current) voltage source. The capacitor is initially uncharged. As soon as the switch is closed, current flows to and from the initially uncharged capacitor.
Why does a capacitor discharge slowly?
Why does a capacitor discharge slowly? A capacitor discharges slowly because of its ability to store electrical charge. When a capacitor is fully charged, it contains an electric field that opposes the flow of current. As the capacitor discharges, the electric field weakens, allowing more current to flow and resulting in a slow discharge. 2. How does the …

capacitance
The capacitor only works right if we pretend that it''s some sort of wire. With wires, if we try to push in more charge than we remove, both ends of the wire immediately charge up to fantastic values of voltage, and this blocks any further current. A capacitor in electronics does the same thing. More: the engineer''s capacitor. Why does this ...
