Currently, capacitors are widely used in the production of high-tech electrical equipment for modern cars. They are included in the design of electronic control units for the operation of the power plant, in the transistor ignition switch, in the power supply circuit of audio equipment, and are also used as starter batteries (supercapacitors).

Instructions
Step 1
The operation of any stabilized power supply unit is unthinkable without the inclusion of a capacitor of a certain capacity in its electrical circuit. The functioning of the specified radio component can be compared with the operation of a suspension shock absorber, which dampens unwanted body vibrations while driving on an uneven road. The capacitor is also designed to smooth out voltage drops in a certain section of the electrical circuit. Periodically accumulating, and giving back to the circuit, electricity.
Step 2
Progress does not stand still, and the increased need for capacitors pushed manufacturers to develop new technologies for the production of these radio components. There are many different types and models of capacitors on the market today. But, despite this, all of them are united by indicators of electrical characteristics. To which you should just pay attention when choosing a radio component for the implementation of the tasks.
Step 3
First of all, the consumer needs to decide on the type of capacitor to be selected. It can be as electrolytic. ceramic, mica or other type of capacitor. At the next stage, the breakdown voltage of the capacitor insulation and its capacitance are determined.
Step 4
Let's take a look at this step using an example of capacitor selection for powering car audio playback devices.
Step 5
To stabilize the voltage of the consumed electricity by the devices in question, an electrolytic-type capacitor is required that can withstand a voltage of 12 volts. And its capacity is calculated by the formula: 1 kilowatt of power is equal to 1 farad.
