Inductors do not behave the same way as resistors do. What you see here is a battery a light bulb a coil of wire around a piece of iron yellow and a switch.

However the small dimensions limit the inductance and it is far more common to use a circuit called a gyrator that uses a capacitor and active components to behave similarly to an inductor.
Why use inductor in circuits. Hence the voltage v is. They are used to block ac while allowing dc to pass. They are also used in electronic filters to separate signals of different frequencies and in combination with capacitors to make tuned circuits used to tune radio and tv receivers.
Therefore inductor use as current filter. Whereas resistors simply oppose the flow of current through them by dropping a voltage directly proportional to the current inductors oppose changes in current through them by dropping a voltage directly proportional to the rate of change of current. To understand how an inductor can work in a circuit this figure is helpful.
What is the purpose of an inductor. Inductor is having the property of inductor does not allow the instant current changes. Why inductors are using in a filtering circuit and vfds as we know the inductor stores the energy and release the same in terms of magnetic field.
The coil of wire is an inductor. Here i change with respect to time. The core could be just air or it could be a magnet.
When you apply a current through the inductor a magnetic field is created around it. See this and over 140 engineering technology simula. If you have read how electromagnets work you might recognize that the inductor is an electromagnet.
Inductors designed for this purpose are called chokes. An inductor is just a coil of wire around some kind of core. Also the voltage across an inductor is v the inductance of the coil l and the current flowing through an inductor is i.
Why inductor use as filtering circuit. Regardless of the design because of the low inductances and low power dissipation on die inductors allow theyre currently only commercially used for high frequency rf circuits. Learn more about how inductors work within a circuit and inductance.
By using a magnetic core the magnetic field will be much much much stronger. Generally inductors are come in the form of chokes and which use to filter current transient typically instant current flow through changes.
