For a 1 kΩ resistor and a 1000 µF capacitor, the time constant is 1 second.
Why do Capacitors discharge?
If you''re asking about self-discharge (when nothing is connected to the capacitor), it''s because the dielectric between the capacitor plates is not perfectly non-conductive, so it acts like a (often very high-valued) resistor connected between the capacitor terminals, and again the potential difference across it causes a current to flow through it.
