The capacitor charges when connected to terminal P and discharges when connected to terminal Q. At the start of discharge, the current is large (but in the opposite direction to when it was charging) and gradually falls to zero. As a capacitor discharges, the current, p.d and charge all decrease exponentially. This means the rate at which the current, p.d or charge

6 FAQs about [Analysis of capacitor discharge speed factors]
How do you calculate the time to discharge a capacitor?
This tool calculates the time it takes to discharge a capacitor (in a Resistor Capacitor network) to a specified voltage level. It’s also called RC discharge time calculator. To calculate the time it takes to discharge a capacitor is to enter: The time constant τ = RC, where R is resistance and C is capacitance.
What if a capacitor discharges a small current?
*In the case of small current discharge, it needs to consider the discharge current of the capacitor (self-discharge). The motion back up, such as RAM and RTC is generally constant current. As an example, charging DB series 5.5V 1F with 5V and discharge until 3V with 1mA of constant current.

What factors affect the rate of charge on a capacitor?
The other factor which affects the rate of charge is the capacitance of the capacitor. A higher capacitance means that more charge can be stored, it will take longer for all this charge to flow to the capacitor. The time constant is the time it takes for the charge on a capacitor to decrease to (about 37%).
