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.
Let us see the different applications of capacitors. Some typical applications of capacitors include: 1. Filtering: Electronic circuits often use capacitors to filter out unwanted signals. For example, they can remove noise and ripple from power supplies or block DC signals while allowing AC signals to pass through.
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 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.
In electrical grids, capacitors helps in stabilizing voltage and power flow. Large-scale capacitors are used to store excess energy and release it when demand peaks to ensure a consistent power supply. This is important for preventing blackouts and managing the variability of power sources.
The capacitors act as a local reserve for the DC power source, and bypass AC currents from the power supply. This is used in car audio applications, when a stiffening capacitor compensates for the inductance and resistance of the leads to the lead-acid car battery. In electric power distribution, capacitors are used for power factor correction.

In single phase squirrel cage motors, the primary winding within the motor housing is not capable of starting a rotational motion on the rotor, but is capable of sustaining one. To start the motor, a secondary winding is used in series with a non-polarized starting capacitor to introduce a lag in the sinusoidal current through the starting winding. When the secondary winding is placed at an ang…

When an electric current flows into the capacitor, it charges up, so the electrostatic field becomes much stronger as it stores more energy between the plates. Likewise, as the current flowing out of the capacitor, discharging it, the potential difference between the two plates decreases and the electrostatic field decreases as the energy moves out of the plates. The property of a capacitor …
