Capacitors are widely used in various electronic circuits, such as power supplies, filters, and oscillators. They are also used to smooth out voltage fluctuations in power supply lines and to store electrical energy in devices such as cell phones and laptops. In short, capacitors have various applications in electronics and electrical systems.
Following are the different applications of capacitor used in different electronics circuits: Energy Storage: Capacitors are able to store electrical charge, which can be used to power various electronic devices. They can quickly discharge the stored energy when needed, making them ideal for use in high-power applications.
Capacitors are connected in parallel with the DC power circuits of most electronic devices to smooth current fluctuations for signal or control circuits. Audio equipment, for example, uses several capacitors in this way, to shunt away power line hum before it gets into the signal circuitry.
They can also be used in charge pump circuits as the energy storage element in the generation of higher voltages than the input voltage. Capacitors are connected in parallel with the DC power circuits of most electronic devices to smooth current fluctuations for signal or control circuits.
Capacitors are used to filter out noise from a DC power supply. By connecting a capacitor across the DC power supply, high-frequency noise will be shorted to the ground while the DC signal passes through unaffected. When a circuit with an inductor connected is abruptly opened, the current passing through the coil diminishes quickly.
Capacitors function based on the principle of capacitance, which is the ability to store charge per unit voltage. When connected to a power source, capacitors charge and discharge according to the applied voltage and the capacitance value. Here some wide applications for capacitors in the following:
