types of capacitors

Capacitors, used in radios, are divided into two main groups: fixed capacitors (constant) capacitance and capacitors, the capacity of which, if necessary, can vary within certain limits - variable capacitors. In turn, constant capacitors are divided into different groups (or types)… Continue Reading

Электрическая емкость. Capacitors

As known, если изолированному проводнику сообщить электрический заряд (t. it is. создать у него избыток или недостаток электронов), то вокруг проводника образуется электрическое поле, а сам проводник приобретет потенциал. clear, что чем больше величина заряда проводника q, тем больше будет егоContinue Reading

resistance, used in radios

The electrical circuits of radio equipment to obtain the desired values ​​of current or voltage is necessary to increase the resistance of the individual circuit portions. For this purpose specially made resistance, which differ both in design, and in the electric data. Resistance is divided into two main types:… Continue Reading

fuses

Any source of electric energy, as well as the wire, connecting it with consumers, always calculated on the maximum permissible current, above which may lead to accident conditions. However, there may be cases, когда в электрической цепи в результате значительного уменьшения ее сопротивления токContinue Reading
