## What is the main function of inductor?

An inductor has the functions of developing electromotive force in the direction that reduces fluctuation when a fluctuating current flows and storing electric energy as magnetic energy.

## Which of the following is the characteristic of inductors or capacitors?

Inductors have the exact opposite characteristics of capacitors. Inductors store energy in a magnetic field (produced by the current through wire), whereas capacitors store energy in an electric field (produced by the voltage between two plates).

## What is inductance and its properties?

An inductor also called a choke, coil or reactor is a passive electronic component with two terminals. It is a component that stores energy in the form of a magnetic field when electric energy flows through it. An inductor has a coil of wire wound around a core.

## What are the characteristics of the inductor when connected to a DC source?

Inductor works on the principle of changing flux, Since in a DC direction of current is constant so magnetic flux will not change. When DC is used in a circuit having an inductor the inductor will offer no impedance/resistance and it will behave as a short-circuited path.

## What are the characteristics of capacitors?

## What is the unit of inductor?

henry
The standard unit of inductance is the henry, abbreviatedH. This is a large unit. More common units are the microhenry, abbreviated ÂµH (1 ÂµH =106H) and the millihenry, abbreviated mH (1 mH =103 H).

## Which of the following factors determine the capacitance of a capacitor?

The capacitance of a capacitor is affected by the area of the plates, the distance between the plates, and the ability of the dielectric to support electrostatic forces.

## Which of the following is not a factor that determines the capacitance of a capacitor?

The curvature of the plates means the plate is spherical plates or the cylindrical plates. So, that the type of the material of the plates is the only factor that does not affect the capacitance of the capacitor.

## What affects the inductance of a capacitor?

Factors Affecting Coil Inductance

They include the number of turns in the coil, the diameter of the coil, the coil length, the type of material used in the core, and the number of layers of winding in the coils.

## What two factors determine the capacitive reactance of a capacitor?

Capacitive reactance is measured in ohms of reactance like resistance, and depends on the frequency of the applied voltage and the value of the capacitor.

## Why dielectric is used in capacitor?

A dielectric material is used to separate the conductive plates of a capacitor. This insulating material significantly determines the properties of a component. The dielectric constant of a material determines the amount of energy that a capacitor can store when voltage is applied.

## What is another name for a capacitor?

The capacitor was originally known as a condenser or condensator. This name and its cognates are still widely used in many languages, but rarely in English, one notable exception being condenser microphones, also called capacitor microphones.

## What is inductor and its type?

The inductor is also called a choke, reactor or just coil. Also Read: Induction. An inductor is described by its distinctive nature of inductance, which is defined as the ratio of the voltage to the rate of change of current. Inductance is a result of the induced magnetic field on the coil.

## How does inductor store energy?

Inductors Store Energy. The magnetic field that surrounds an inductor stores energy as current flows through the field. If we slowly decrease the amount of current, the magnetic field begins to collapse and releases the energy and the inductor becomes a current source.

## Which is the example for inductor?

Solution : Inductor is a device used to store energy in a magnetic field when an electric current flows through it. The typical examples are coils, solenoids and toroids.

## What is inductor formula?

The inductor equation tells us: v = L d i d t v = \text L\,\dfrac{di}{dt} v=Ldtdi. This says the voltage across an inductor is proportional to the rate of change of the current through the inductor. Since the current source provides a constant current, the rate of change, or slope, of the current is 0.

## What is inductor and its formula?

Thus, the magnetic inductance formula defines as the proportion between the magnetic flux in the element plus the electric current which circulates through the element. Therefore, the equation will be: L = Î¦N/I.
