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
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 его… Continue Reading
Stream of electrically charged particles - electrons or ions - called orderly movement of a number of these particles in a certain direction. The concept of flow in this case is opposed to the notion of random motion of particles in different directions, in which there is no preferential direction. to make… Continue Reading
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
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 ток… Continue Reading
