Inductance is one of the important components of the circuit, which plays a very important role in frequency response, resonant circuit and other circuits. To measure inductance, there are a variety of experimental methods to choose from, the most common is the use of LCR bridge and simple RLC circuit measurement.
When using LCR bridge, it is necessary to select the appropriate test capacitor according to the size of the inductance, adjust the balance state of the bridge, and observe the level change through the oscilloscope to obtain the inductance value. When using a simple RLC circuit measurement, it is necessary to calculate the resistance and capacitance of the circuit according to a certain formula, and the value of the inductance is determined by the relationship between the frequency and the output voltage.
In short, different inductance measurement methods have their own advantages and disadvantages, in the actual measurement needs to choose the appropriate method according to the specific situation.
