Катушка индуктивности – это винтовая, спиральная или винтоспиральная катушка из свернутого изолированного проводника, обладающая значительной индуктивностью при относительно малой емкости и малом активном сопротивлении. Такая система способна накапливать магнитную энергию при протекании электрического тока.
Катушка индуктивности в электрической цепи хорошо проводит постоянный ток и в то же время оказывает сопротивление переменному току, поскольку при изменении тока в катушке возникает ЭДС самоиндукции, препятствующая этому изменению.
Основным параметром катушки индуктивности является ее индуктивность, которая определяет, какой поток магнитного поля создает катушка при протекании через нее тока силой 1 ампер. Типичные значения индуктивностей катушек от десятых долей мк Гн до десятков Гн.
Катушки индуктивности (совместно с конденсаторами и/или резисторами) используются для построения различных цепей с частотно-зависимыми свойствами, в частности, фильтров, цепей обратной связи, колебательных контуров и т. п.
Катушки индуктивности используются в импульсных стабилизаторах как элемент, накапливающий энергию и преобразующий уровни напряжения.
Две и более индуктивно связанные катушки образуют трансформатор.
Катушка индуктивности, питаемая импульсным током от транзисторного ключа, иногда применяется в качестве источника высокого напряжения небольшой мощности в слаботочных схемах, когда создание отдельного высокого питающего напряжения в блоке питания невозможно или экономически нецелесообразно. В этом случае на катушке из-за самоиндукции возникают выбросы высокого напряжения, которые можно использовать в схеме, например, выпрямив и сгладив.
Катушки используются также в качестве электромагнитов.
Катушки применяются в качестве источника энергии для возбуждения индуктивно-связанной плазмы.

Give the summary of the text.
Inductance is the property of an electrical circuit causing voltage to be generated proportional to the rate of change in current in a circuit. This property also is called self inductance to discriminate it from mutual inductance, describing the voltage induced in one electrical circuit by the rate of change of the electric current in another circuit.
The
quantitative definition of the self inductance
of an electrical circuit in SI units (weber’s per ampere, known as
henries) is
where v denotes the voltage in volts and i the current in amperes. This is a linear relation between voltage and current akin to Ohm’s law, but with an extra time derivate. The simplest solutions of this equation are a constant current with no voltage or a current changing linearilly in time with a constant voltage.
The
term ‘inductance’ was coined by Oliver Heaviside in February
1886. It is customary to use the symbol
for inductance, possibly in honour of the physicist Heinrich Lenz.
The SI unit of inductance is the henry
(
),
named after American scientist and magnetic researcher Joseph Henry.
.
Inductance is caused by the magnetic field generated by electric currents according to Ampere’s law. To add inductance to a circuit, electronic components called inductors are used, typically consisting of coils of wire to concentrate the magnetic field and to collect the induced voltage. This is analogous to adding capacitance to a circuit by adding capacitors. Capacitance is caused by the electric field generated by electric charge according to Gauss’s law.
