Why does capacitor charge slowly but discharge quickly?
$begingroup$ @ammarx The rate at which the capacitor charges or discharges is the amount of current flowing through it. When the input voltage is switched high this current is limited by the 100k resistor and as it charges the voltage across the resistor falls so less current flows and the capacitor charges more slowly.

How can I quickly and safely discharge a charged capacitor …
I am learning how to use capacitors (ceramic and electrolytic from 1pf - 1000uf) and am trying out various experiments using a breadboard. I am constantly adding/removing things to my layout to see... With small capacitors up to 1 mF, there is little to worry about.
voltage
As far as I understand, in an AC circuit, a capacitor is supposed to charge as the voltage is increasing, and as soon as the voltage starts decreasing, the capacitor starts to discharge (Since it will be the higher voltage source out of all in the circuit by then). But in a
Discharging a Capacitor (Formula And Graphs)
What is Discharging a Capacitor? Discharging a capacitor means releasing the stored electrical charge. Let''s look at an example of how a capacitor discharges.

Physics A level revision resource: Introduction to capacitors
A battery stores electrical energy and releases it through chemical reactions, this means that it can be quickly charged but the discharge is slow. Unlike the battery, a capacitor is a circuit component that temporarily stores electrical energy through distributing charged particles on (generally two) plates to create a potential difference.
