There are many application examples of capacitors in daily life:

Rechargeable devices, such as rechargeable flashlights and shavers, use capacitors to store electrical energy.

Solar energy products: The battery, also known as the capacitor, in solar street lights is used to store the energy collected from the solar panel and release it for use by the lights at night.

Electronic devices: Many electronic devices, including fluorescent lamps, use capacitors to increase startup voltage or act as filters in circuits.

Household appliances: Devices such as electric fans and electric motors are also equipped with capacitors, which help stabilize the operation of the equipment.

Audio equipment: In audio systems, coupling capacitors are used to prevent DC offset voltage from entering the speaker, ensuring sound quality.

Power supply: In some backup power sources or devices that require fast response energy, capacitors can be used as temporary batteries.

Filtering and Power Factor Correction: Capacitors can also be used for high pass and low-pass filters, as well as power factor correction, to optimize power transmission and usage efficiency.

Starting the motor: When starting an induction motor, the capacitor can provide the required additional current to help accelerate the motor's start.

DC power supply filtering: In DC power supply, capacitors are used to filter out high-frequency noise and ensure the purity of the DC signal.

Other electronic devices: the tuning circuit of transistor radios and the coupling circuit of high-frequency televisions also require capacitors.

In summary, capacitors play an important role in our daily lives, not only limited to the aforementioned applications, but also for many other purposes.
