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.
Contact UsDo capacitors automatically release their energy over time?
In theory it will. If an ideal capacitor is charged to a voltage and is disconnected it will hold it''s charge. In practice a capacitor has all kinds of non-ideal properties. Capacitors have ''leakage resistors''; you can picture them as a very high ohmic resistor (mega ohm''s) parallel to the capacitor. When you disconnect a capacitor, it will be ...

Where A is the area of the plates in square metres, m 2 with the larger the area, the more charge the capacitor can store. d is the distance or separation between the two plates..

why is always the charge redistribution occurs symmetrically on both the plates?

why does charge stored in capacitor remain constant. Because you disconnected the voltage source. It''s meant to be implied that the capacitor is disconnected from all external circuits. Therefore there''s nowhere for the charge to go. And since charge is a conserved quantity, that means the charge on the capacitor plate must remain constant.

If the capacitor is charged to a certain voltage the two plates hold charge carriers of opposite charge. Opposite charges attract each other, creating an electric field, and the attraction is stronger the closer they are. If the distance becomes too large the charges don''t feel each other''s presence anymore; the electric field is too weak.
