Characteristics of Inductors: Introduction to Current and Voltage in Inductors 2

V = L * di/dt

Among them, V represents the voltage of the inductor, L represents the inductance, and di/dt represents the rate of change of the current. This formula indicates that when the current changes, the inductor will generate a voltage, and the magnitude of this voltage is related to the inductance of the inductor and the rate of change of the current.  diode

3. Frequency response:

The frequency response of an inductor refers to its ability to respond to changes in current at different frequencies. In the low frequency range, inductors exhibit lower impedance, making it easier for current to pass through; In the high-frequency range, the impedance of the inductor increases, making it difficult for current to pass through. This is because as the frequency increases, the rate of current change also increases, causing the inductor to generate a larger voltage and hindering the flow of current.diode

4. Energy storage:

Inductors are components capable of storing energy. When current passes through an inductor, magnetic field energy is stored in the inductor, which can be released when the current changes. The energy storage capacity of an inductor is related to its inductance value, current magnitude, and rate of change.diode
