What kind of inductor original?

- Aug 01, 2018 -

Inductor is a device that inducts electrical energy to be stored as magnetic energy.the inductor is similar to a transformer in structure, but has only one winding.inductor has certain inductance, it only blocks the change of current.if the inductor is in a state where there is no current, it will try to block the current from flowing through it when the circuit is switched on.if the inductor is in a current state, it will try to keep the current constant when the circuit is disconnected.inductor also called choke, reactor, dynamic reactor.

 

Self inductance device

When a current passes through the coil, a magnetic field is generated around the coil.when the current in the coil changes, the magnetic field around it also changes correspondingly. The magnetic field of this change can make the coil generate induced electromotive force (induced electromotive force) (electromotive force is used to represent the terminal voltage of the ideal power supply of the active element), which is self-inductance.

 

Transformer

When two inductor coils are close to each other, the magnetic field change of one inductor coils will affect the other inductor coils, and this effect is mutual inductance.the size of mutual inductance depends on the degree of coupling between the inductance coil and two inductor coils.
