Capacitor Discharge
If we discharge a capacitor, we find that the charge decreases by half every fixed time interval - just like the radionuclides activity halves every half life. If it takes time t for the charge to decay to 50 % of its original level, we find that the charge after another t seconds is 25 % of the original (50 % of 50 %).
quick charge but slow discharge of a capacitor
Put two resistors in series with the cap and then put a diode in parallel with one of the resistors. This will give you a different time constant depending on if current is flowing in to or out of the capacitor - …
Introduction to Capacitors, Capacitance and Charge
charge on a cap is a linear product of capacitance and voltage, Q=CV. If you plan to drop from 5V to 3V, the charge you remove is 5V*1F - 3V*1F = 2V*1F = 2 …
