What are the functions of inductors? What are the functions of inductors?
Release time: May 28,2024
The main function of the inductor is to isolate and filter AC signals or to form a resonant circuit with capacitors, resistors, etc.
1. The reason why an inductor works is that it produces a changing magnetic field when it passes an unsteady current, and this magnetic field will in turn affect the current. Therefore, in this way, any conductor, as long as it passes an unsteady current, will A changing magnetic field will be produced, which will in turn affect the current, so any conductor will have self-induction;
2. The characteristics of the inductor are exactly opposite to those of the capacitor. It has the characteristics of preventing the passage of alternating current and allowing the smooth passage of direct current. The characteristics of the inductor are to pass DC and resist AC. The higher the frequency, the greater the coil impedance. Inductors often work together with capacitors in circuits to form LC filters, LC oscillators, etc. In addition, people also use the characteristics of inductors to create chokes, transformers, relays, etc.
