The main purpose of having a capacitor in a circuit is to store electric charge. For intro physics you can almost think of them as a battery. . Edited by ROHAN
Capacitance and energy stored in a capacitor can be calculated or determined from a graph of charge against potential. Charge and discharge voltage and current graphs for capacitors.
Discharging a capacitor can be thought of as similar to charging. That is, about 63.21% of the total capacity is discharged during the time constant, and when it is discharged about 5 times the time constant, approximately 99.33% of the
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

Charging a Capacitor Method 1. Set up the circuit as shown in the diagram. 2. Close the switch to charge the capacitor, record the voltage and current at time t = 0 and at 5 s intervals as the capacitor charges until about 120s have passed. This may be made easier by working in pairs. 3. Repeat the experiment twice more and record the voltage

Charging and Discharging of Capacitor - Learn about what happens when a capacitor is charging or discharging. Get a detailed explanation with diagrams.
Since Q = CV, a large capacitor charged to a huge voltage stores a lot of charge, which will lead to a high initial charging or discharging current, with consequent heating effect. The values used in the film (and noted above) offer a good guide to what works well – and safely.
Capacitors can still retain charge after power is removed which could cause an electric shock. These should be fully discharged and removed after a few minutes A student investigates the relationship between the potential difference and the time it takes to discharge a capacitor. They obtain the following results:
The capacitor should initially be fully discharged Charge the capacitor fully by placing the switch at point X. The voltmeter reading should read the same voltage as the battery (10 V) Record the voltage reading every 10 s down to a value of 0 V. A total of 8-10 readings should be taken
Thus, theoretically, the charge on the capacitor will attain its maximum value only after infinite time. When the key K is released [Figure], the circuit is broken without introducing any additional resistance. The battery is now out of the circuit, and the capacitor will discharge itself through R.
In their experiments, both Alom and Carol do without a two-way switch and instead simply disconnect the capacitor from the power supply to make it discharge through the resistor. As Alom mentions in the introduction, the uses of capacitors are quite interesting for giving the students some context here. He refers to a previous film:
Capacitors provide temporary storage of energy in circuits and can be made to release it when required. The property of a capacitor that characterises its ability to store energy is called its capacitance. When energy is stored in a capacitor, an electric field exists within the capacitor.
