Capacitors are used for coupling and decoupling purposes in circuits. Coupling capacitors are employed to transfer AC signals between different stages of a circuit while blocking DC voltages.
Capacitors play a crucial role in electronic circuits in several ways. Firstly, they store electrical energy for later use. This is particularly useful in power supply circuits where they smooth out the output of power supplies. Secondly, they block direct current (DC) and allow alternating current (AC) to pass through in AC circuits, a property utilised in many radio frequency applications.

In terms of power system, the function of the capacitor is to improve the quality of the electrical system.
The stored energy is released as current flows back out of the capacitor. Capacitors block direct current (DC) while allowing alternating current (AC) to pass – at least for a short time while the capacitor charges and discharges. This property makes capacitors highly useful in filtering applications for power supplies and audio equipment.
A little change in the voltage levels may null function the circuit. If the input signal contains DC voltage. This DC voltage may disturb the biasing of our amplifier circuit. To avoid such a situation, we put a capacitor to block that DC. Remember, capacitors always act open to DC signals. It doesn’t allow any DC to pass through it.
In such a situation, capacitors are very useful. The reason is capacitors easily charge and discharge and can give you a discharge rate in milliseconds. So if you are in a situation where you need to draw a high amount of current, then a capacitor would be a component you must consider.
These charges create a potential difference across the plate of a capacitor. Due to this potential difference, the capacitor acts as a voltage source in the circuit. This function of a capacitor is very useful when we want to double the output voltage, triple the output voltage, or just want to have a constant voltage level for reference purposes.
