In an electronic circuit there are usually many different components fitted in the circuit, but usually there are 3 main components that are best known as resistors, coils and capacitors. Each component brings a different use to the circuit, which is resistance, inductance and electricity applied to each of the above components. In which inductance is often interested by many people and want to know what is the meaning of the inductance value is? Today TTTT Global will explain to you the meaning of inductance and what is the unit of inductance.

What is the inductance and the meaning of the inductance value?


Inductance created from an inductor (coil, magnetic coil, inductor) is a passive electronic component that creates an electrical conductor with a certain number of turns and whose main effect is to generate a magnetic field. when a current flows through it. Inductors carry a certain inductance. This is the electronic device that creates the inductance in the electromagnetic circuit.

Inductance TTTT, also known as magnetic inductance, occurs in a closed circuit with alternating current flowing through. An inductor is characterized by its inductance. Inductance is calculated using the formula as voltage divided by the rate of change of current. The inductor is one of the main passive components (coils) in an electronic system. The basic passive components in electronics are resistors, capacitors and inductors.

What is the meaning of inductance value?

What is the meaning of inductance value? The meaning of the inductance value is to indicate the ability of the coil to accumulate energy from the magnetic field. The higher the number of turns in the inductor and the greater the current flowing, the greater the inductance value. The symbol for inductance is L and the unit of inductance is Henry (H).

What is inductance? Inductance, also known as magnetic inductance, is a phenomenon that occurs only in electrical circuits with alternating current flowing through in a closed circuit or when conducting a DC circuit breaker, it also produces the phenomenon of inductance. The variation of the amperage produces a change in the magnetic flux in the circuit.

Construction and classification of inductors, inductance

Điện cảm

Based on the structure and scope of application, people divide inductors into the following main types:

  • Acoustic inductor.
  • Medium frequency inductor.
  • High frequency inductor.
  • Sorting by shape we have plug type and stick type.
  • Classified by structure there are cored and non-cored types (Mecc Alte Alternator).

Working principle of inductor

When connected to a DC current, the inductor will act as a resistor with a reactance of zero. Since the amperage in a DC circuit is constant in time, the magnetic field due to the current passing through the conductor of the DC circuit. The inductor has constant magnitude and direction.

When connected to alternating current, the inductor will generate a magnetic field and an electric field that varies with the corresponding frequency of the current flowing through the device. The direction of the electric field will always be perpendicular to the magnetic field generated at the inductor.
