Charge and Discharge
How a capacitor gets its charge. When a capacitor is connected in a DC circuit as in Fig 2.2.1, a large current will flow, but only for a short time. Electrons begin to flow from the negative battery terminal, and appear to be flowing around the circuit.
Physics A level revision resource: Introduction to capacitors
A capacitor is characterised by its capacitance (C) typically given in units Farad. It is the ratio of the charge (Q) to the potential difference (V), where C = Q/V The larger the capacitance, the more charge a capacitor can hold. Using the setup shown, we can measure the voltage as the capacitor is charging across a resistor as a function of ...
How to Safely Discharge a Capacitor | DigiKey
Fortunately, this capacitor discharge calculator makes this step a lot easier. You will need to know the capacitance, initial charge voltage placed on the capacitor, safety threshold voltage (voltage at which the capacitor is considered safely discharged), and either the resistor value or the discharge time you want to achieve.

How to Discharge a Capacitor
How to Discharge a Capacitor. To discharge a capacitor, unplug the device from its power source and desolder the capacitor from the circuit. Connect each capacitor terminal to each end of a resistor rated at 2k ohms using wires with alligator clips. Wait for 10 seconds for a 1000µF capacitor to discharge.
circuit analysis
Current is the rate of charge flow. If there is current then there is a movement of charge from the battery to the capacitor. The relationship between charge, capacitance and voltage is given by $ Q = CV $. For a given capacitor value the charge and voltage are proportional.
