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.
