Inductor characteristics

The characteristics of the inductor are exactly opposite to those of the capacitor. It has the characteristic of preventing the passage of alternating current and allowing the direct current to pass smoothly. When the DC signal passes through the coil, the resistance of the wire itself is small. When the AC signal passes through the coil, the self-induced electromotive force will be generated at both ends of the coil. The direction of the self-induced electromotive force is opposite to the applied voltage, which hinders the passage of AC. Therefore, the characteristics of the inductor are DC and resistance AC. The higher the frequency, the larger the coil impedance. The inductor often works with the capacitor in the circuit to form an LC filter, an LC oscillator, and the like. In addition, people also use the characteristics of the inductor to manufacture chokes, transformers, relays and so on.

Through DC: It means that the inductor is in the off state of DC. If the resistance of the inductor is not counted, the DC can pass through the inductor “unimpeded”. For DC, the resistance of the coil itself is very little hinder to DC. It is often ignored in circuit analysis.

Resisting AC: When the AC power passes through the inductor, the inductor has an obstructive effect on the AC power. The AC current is the inductive reactance of the inductor.
