Characteristics of Inductors Introduction to Current and Voltage in Inductors 2

V = L * di/dt

In this formula, V represents the voltage of the inductor, L denotes the inductance, and di/dt indicates the rate of change of current. It demonstrates that when the current changes, the inductor generates a voltage, the magnitude of which depends on the inductance of the inductor and the rate of current change.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, the inductor exhibits lower impedance, allowing current to pass easily; whereas in the high-frequency range, the inductor's impedance increases, making it difficult for current to pass. This occurs because as the frequency rises, the rate of current change also increases, causing the inductor to generate a higher voltage that opposes the current flow.diode

4. Energy Storage:

An inductor is a component capable of storing energy. When current flows through the inductor, magnetic field energy is stored within it, which can be released when the current changes. The energy storage capacity of an inductor is related to its inductance value, the magnitude of the current, and the rate of change of the current.diode
