Answer to AIM To investigate the discharge of a capacitor
Yes, capacitors discharge on their own over time. This is due to the natural leakage of electrical current through the dielectric material that separates the two plates of a capacitor. However, if you need to quickly discharge a capacitor, there is a simple way to do it using a screwdriver.
The best way to select a proper resistor is to use this formula: P = V²/R, where P is the power in watts, V is the voltage across the resistor, and R is the resistance in ohms.. For example, let''s say you''re discharging a capacitor with a voltage of 25V. If you wanted to use a 100ohm resistor, then you would need a power rating of at least 0.25W (25V/100ohms = 0.25).

Answer to AIM To investigate the discharge of a capacitor
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 decreases is proportional to the amount of current, p.d or charge it has left

The capacitor''s secure discharge is as basic as adding some resistance load to the terminals, which will dissipate the energy included in the capacitor. A high resistance receiver could be utilized to discharge the capacitor. Moreover, the charge included in the plates will take a longer time to discharge.

So how can capacitor act as a short circuit in the long term when in the end we have an open circuit? And because of the fact that the mother nature needs some time to "create" the electric field (voltage) across the capacitor plates. Some time is needed to charge the capacitor to the voltage level we connect the capacitor.
